VOLUME XXIX.
A CONTRIBUTION TO THE KNOWLEDGE OF THE
ORTHOPTERA OF MEXICO AND CENTRAL AMERICA.
BY JAMES A. G. REHN.
This paper contains the results of a study of 464 specimens, princi-
pally from the collection of the author (now presented to the Academy
of Natural Sciences of Philadelphia >, beside a small quantity of ma-
terial in the collection of the Academy, and an interesting series of
118 specimens belonging to the United States National Museum,
loaned through the kindness of Mr. W. H. Ashmead of that insti-
tution. The specimens from the United States National Museum
are designated by the initials of that institution, while those from
the author's collection are unmarked.
The original intention of the author was to make this paper a
faunistic study, but many new species and records forced themselves
into view, and the conclusion was reached that the present time is
too premature for such studies in the region under consideration.

Ancistrogaster sp.
One immature 9 ; Jalapa, Vera Cruz, Mexico. Collected by J.
T. Mason (U. S. N. M.).
»olohopliora ruficeps (Burmeister).
1838, F[orficnla] ruficeps Burmeister, Handb. cler Ent., ii, p. 755.
Two males ; Jalapa, Vera Cruz, Mexico Collected by J. T.
Mason (U. S. N. M.).
These specimens are quite uniformly colored, the only apparent
contrast being the reddish head. In one specimen the forceps are
much shorter (7.75 mm.) than in the other (12.5 mm.).
Apterygida linearis (Eschscholtz).
1822, Forficula linearis Eschscholtz, Entoniographien, i, p. 81.
Forficula tseniata Dohrn, Stettin Ent. Zeit., xxiii, p. 230.
Sixteen specimens; Jalapa, Vera Cruz, Mexico. August, and
September. Collected by Otis W . Barrett. (Eight; three males,
five females.) Same locality. Collected by J. T. Mason. (Two; £
and ?.) (U. S. N. M.) Texolo, Vera Cruz, Mexico. 1899. Col-
lected by S. N. Rhoads (1<?). Cuernavaca, Morelos, Mexico.
September. Collected by Otis W. Barrett (5 males).
Bormans and Krauss* have rather vaguely noticed that the name
linearis of Eschscholtz was based on the same insect as Dohrn's
fa ii in ta, a fact which cannot be questioned when the original de-
scription of linearis is examined. All the characters assigned are
perfectly recognizable, the size alone being somewhat unusual,
though the writer has examined specimens but little larger.
Apterygida californica (Dohrn).
1865, F[orficuld] Californica Dohrn, Stettin Ent. Zeit., sxvi, p. 85.
Two specimens, $ and 9 ; Gualan, Guatemala. Collected by
Mrs. S. P. McElroy (U. S. N. M.).
These specimens extend the range of the species south of the
former southern limit — Teapa, Tabasco, Mexico.
Family BLATTID^E.
Pseudoinops oblongata* (Linnaeus).
1758, [Blatta] oblongata Linnseus, Syst. Nat,, x ed., p. 425.
Four specimens; Orizaba, Vera Cruz, Mexico. January 9-16,
1S92. Collected by H. Osborn (U. S. N. M.) (2). Cuernavaca,
Morelos, Mexico. September. Collected by Otis W. Barrett (2).

AMERICAN ORTHOPTERA. 6
The specimens from Cuernavaca belong to the form which Saus-
sure calls variety C (Miss. Scient. Mex., Orth., p. 50).*
IVyctibora noctivaga n. sp.
Type, $ ; Machuca, San Juan River, Nicaragua. Collected by
Dr. J. F. Bransford (Acad. Nat. Sciences, Phila.) Allied to N.
mexieana and azteca, but much larger than either. From mexicana
it is distinguished by possessing an interspace between the eyes, and
by having the pronotum somewhat produced anteriorly. From
azteca it is distinguished principally by the very much greater size.
Size large. Head small, posteriorly produced; eyes almost contiguous; an-
tenna? as long as the body, filiform, hirsute. Pronotum broad ; anterior border
somewhat produced, posterior border subtruncate ; entire surface velvety. Teg-
mina extending much beyond the apex of the abdomen, apically rotundate,
costal margin broadly rounded, surface velvety; marginal and discoidal fields
longitudinally veined; anal sulcus arcuate, deeply indicated; anal field semi-
ovate, subglahrous. Wings large, venation prominent. Limbs heavy ; femora
with the spines on the posterior margins much longer than those on the anterior
margins; anterior femora bearing thirteen small spines on the anterior margin,
basal section unarmed ; tibiae bearing prominent spines on all four margins. Ab-
domen heavy, the lateral margins of the four apical segments posteriorly prod need .
Supranal plate triangularly produced, apically emarginate, centrally ridged ; sub-
genital plate large, apex subtruncate;! cerci heavy, acuminate, about twice as
long as the supranal plate.
General color brownish black, shading on the more translucent portions of the
tegmina to vinaceous, the " bloom" being a pale golden tint. Wings with the
discoidal and anterior fields vinaceous; the intercalcate, intermediate and pos-
terior fields transparent, the veins pale brownish. Abdomen with ferrugineous
patches on the lateral portions of the segments. Supranal and subgenital plates
brownish black, which general tint also colors the face, limbs and antenna?.
Measurements :
Length of body 35 mm.

This species is closely related to both E. conspersa and azteca, but
is separated from each by very appreciable characters. The size is
less than E. conspersa, the apex of the anal field is acute instead of
obtuse as in that species, and the supranal and subgenital plates are
both more acuminate. From E. azteca it is separated by the form
of the supranal plate, which is produced and acuminate instead of
rotundate or subtruncate.
Size rather small. Head distinctly visible in front of the pronotum when
dorsally viewed, anterior outline well rounded ; eyes large, considerably sepa-
rated ; antennae filiform, sparsely pilose, over twice as long as the pronotum.
Pronotum large, produced anteriorly, posterior margin triangularly produced,
deflected lobes with the margins broadly rounded. Tegmina exceeding the apex
of the abdomen, rather narrow, apex rounded, costal margin gently arcuate; anal
sulci extended posteriorly, giving the anal field a semi-hastate form. Wings ample,
extending to the tip of the tegmina when in repose. Femora sparsely spined ; an-
terior paii- bearing four spines on the central portion of the lower margin, three
moderately large spines on the upper margin ; median pair bear three centrally
grouped spines on the lower margin, four on the upper; posterior pair with three
spines on each margin, those on the lower margin centrally grouped, the last
spine on the upper margin separated from the other two by a considerable inter-
space. Tibiae heavily spined ; basal tarsal joint set with fine spines, the general
appearance being that of pectination. Supranal plate triangularly produced,
margins somewhat reflexed, apex triangularly emarginate. Subgenital plate
triangularly produced, scoop-like. Cerci slightly exceeding the supranal plate
in length.
General color above tawny-olive.* Pronotum raw umber, very closely and
minutely punctate with brownish black, the punctations being largest on the
periphery. Tegmina regularly punctate with Vandyke brown, the punctations
largest in the anal field and in the distal half of the tegmina, which latter region
contains several larger blotches of the same tint. Wings pellucid, the costal
region slightly suffused with brownish and punctate with pale brownish. Both
aspects of the abdomen blackish brown finely stippled on a brown-gray ground,
the body tint being most noticeable below. Limbs horn, speckled with blackish
brown; the overlying tint being strongest and more suffusing on the distal por-
tions of the tibiae.

These specimens are somewhat doubtfully referred to this very
variable species. One possesses no spines on the lower margin of
the femora, which fact would place it in another section of the
genus, but Saussure and Zehntner inform us that these are obsolete
in some individuals. The maculation of the pronotum is very vari-
able in form and intensity ; in two specimens it is rounded posteriorly,
entirely free from the posterior margin of the pronotum, and with the
antero lateral angles much produced, the third specimen has the pos-
terior margin of the pronotum forming the posterior boundary of the
maculation.

Family PHASMID^.
Serniyle giiatemala> n. sp.
Type, 9 ; Gualan, Guatemala. Mrs. S. P. McElroy (U. S. N.M.).
Apparently closest allied to S. mezicana* Saussure, but differing
in the spiniform interocular processes, and in the absence of any
dorsal foliaceous lobe on the fifth abdomen segment. With the
other species of the genus — saussurii, azteea and strigata — no com-
parison is necessary, the general characters of the head being shared
by mexicana alone.
General build moderately robust, the entire body tuberculate, the tubercles
most numerous anteriorly. Head with six longitudinal rows of tubercles, the
median pair strongest developed, the second tubercle in each row being spini-
form, several spines forming an additional group between the median rows;
antennae about half as long as the body, the basal joint considerably flattened.
Prothorax about as long as broad, the collar slightly constricted ; mesothorax
elongate, over four times as long as the prothorax ; metathorax considerably
shorter than the mesothorax, heavy, showing traces of a median carination which
also extends over the median segment and on the abdomen ; median segment
very short, over twice as broad as long. Abdomen moderately elongate, the
tubercles arranged in four longitudinal rows on the dorsal surface, the lateral
aspect with two longitudinal roughened carinas; fifth segment somewhat inflated,
no foliaceous lobe developed from the medio-dorsal portion of the segment, the
lateral angles being posteriorly produced into rounded posteriorly projecting
lobes. Femora and tibia; multicarinate ; anterior and posterior tibiae slightly
exceeding the femora in length.
General color Vandyke brown, becoming walnut brown on the abdomen ; limbs
and antenna? raw umber.

i\fter an examination of thirty-two specimens of the genus Ma-
choerocera, I have reached the conclusion that sumichrasti of Thomas
is nothing but a phase of this very variable species. The color dif-
ferences as given by Thomas appear to be of no value, while struc
tural differentiations are absent. The median carina of the pronotum
is cut thrice in some specimens, in others twice, while a few have a
very faint trace of the third incision.

the lower margin of the lateral lobes being sinuate (as in Paralexias)
and not straight. The characters of agreement are the interspace
between the mesosternal lobes in the female (open instead of closed),
and in the width of the interspace between the eyes.

PRISTOCEUTHOPHILUS n. gen.
Allied to Hadencecus, Ceuthophilus and Hemiudeopsylla, but pre-
senting quite distinctive characters. It differs from all in the pos-
session of but three pairs of spurs on the posterior tibia?, and in
having a conoid development of the vertex. From Hadencecus it is
separated by the elongate last palpal joint, and by the broadly
emarginate subgenital plate of the male. From Ceuthophilus it
differs in the nou spinous median coxae, and in the very long first
hind tarsal joint. From Hemiudeopsylla difference is noticed in
the absence of spines on the lower external margin of the median
femora, in the absence of serrations on the lower external margin
of the posterior femora, and in the presence of five or more small
spines between the larger spines on the upper margins of the poste-
rior tibise.
Vertex produced into a deflected spinous process, extending
almost as far downward as the lower border of the eyes. Last
palpal joint almost twice as long as its antecedent. Anterior
femora without spines. Median coxa? not spined ; femora smooth,
except for the spine on the apex of the external portion ; tibia?
bearing several closely appressed spines situated around the cen-
tral section. Posterior femora bullate, the lower external margin
non serrate, carrying one (or two) small spines on the apical half;
tibia? bearing many (five to thirteen) small spines between the
larger ones; apical spurs three in number; first tarsal joint very
long, much longer than the remaining portion. Subgenital plate
broadly emarginate.

taken from alcohol and dried. It is clearly not P. validus Saus-
sure and Pictet (Biol. Cent.-Amer., Orth., i, p. 373, tab. xviii, tigs.

Cocconotus ligiiicolor n. sp.
Type : female; Machuca, Nicaragua (Acad. Nat. Sci. Phila.").
Allied to C. cethiops Brunner, but differing in the absence of
black on the basal joint of the antennae and on the vertex and pro-
notum, in the presence of black on the labrum (which is ferrugine-
ous in oethiops), in the presence of four spines (instead of one) on
the anterior femora, and in the very narrowly emarginate tip of the
subgenital plate.
Size medium. Vertex with two basal tubercles rather prominent ; eyes globose.
Pronotum verruculate, centrally constricted, posterior sulcus distinctly marked ;
anterior margin broadly rotundate, posterior subtruncate; lateral lobes longer

C'occonotus hellicosus n. sp.
Type: female; Cocos Island, Pacific Ocean.* February 38, 1891.
Allied to C. striolatus Redtenbacher, from St. Vincent, and C.
globosus Bruner, from Mexico and Guatemala. From the former
it differs in the non-pilose body, in the subdepressed form of the
central part of the pronotum, in the broadly emarginate central
portion of the posterior margin of the same region, the more curved
ovipositor, and the presence of five species on the median femora.
From the latter it differs in the non constricted pronotum, the sub-
truncate posterior margin of the pronotum, and in the triangular
subgenital plate of the female.
Size rather large; general build robust, body glabrous. Head with the vertex
bearing a pair of rotuudate tubercles and an anteriorly directed spinose process;
antennae elongate, subfiliform ; eyes spherical, slightly exserted. Pronotum
strongly rugulose, the lateral lobes smoother than the dorsal aspect; anterior
margin arcuate, posterior subtruucate with a broad central emargination ; lateral
lobes slightly longer than deep, the lower margins subtruncate, central portion
thickened. Tegmina rather long, moderately broad, apex rounded. Wings
ample, reaching almost to the tip of the tegmina. Anterior femora subcorn-
pressed, the external lower margins bearing four spines on the distal portion;
tibiae quadrate, the lower margins spined. Median femora subcompressed, the
external lower margins bearing five spines; tibiae quadrate, the lower margins
spined. Posterior femora considerably expanded basally, the external lower
margin bearing eight large spines on the distal two-thirds; tibia? quadrate, all
margins spined except for a small basal portion, the lower surface with the spines
sparser in numbers than the upper surface. Ovipositor slender, curved, the apex
accuminate, the lower margin with a well-defined basal shoulder. Subgenital
plate triangular-acuminate, deeply and narrowly emarginate apically.
General color yellowish chocolate color, the tegmina and limbs sprinkled with
darker patches of pure chocolate color. Pronotum and head marked with black,
which color suffuses the extreme tip on all the spines on the limbs. Wings pale
grayish hyaline, the longitudinal viens brownish, the periphery touched with
whitish.

AMERICAN ORTHOPTERA. 31
Allied to E. pictipennis Saussure and Pictet,* but possessing
many very distinctive characters. The median and discoidal veins
of the tegmina are centrally almost contiguous; the anterior border
of the pronotum is without a thickened margin ; the basal section of
the subgenital plate is as broad as long, with the carina basally
indistinct, and the styles are heavier.
Size large; general build very slender; head, limbs and antenna- pilose. Head
broad, facial region very much flattened ; eyes subglobose, considerably exserted ;
antennas very long, over twice as long as the tegmina with pronotum and head.
Pronotum strongly tuberculate; anterior margin broadly obtuse-angulate, pos-
terior arcuate ; lateral lobes about twice as long as high, the lower margin thick-
ened, tuberculate, sinuate ; posterior sulcus strongly impressed ; lateral angle on
the metazoua marked. Tegmina elongate, about six times as long as wide ; median
and discoidal veins quite distinct distally and proximally but centrally almost con-
tiguous, the general arrangement of transverse veins forming quadrate or rec-
tangular patterns. Wings very large, about reaching the apex of the tegmina.
Anterior and median femora slender, sulcate beneath, bearing six or seven spines
on the lower external margins, genicular lobes spinose; tibiae very slender, quad-
rate, lower margins spined as is also the case with upper internal margins of the
mediau pair. Posterior femora slender, bearing fourteen or fifteen large spines
on the external margin, the basal portion of which is unarmed ; tibia? quadrate,
spined on the margins. Subgenital plate basally broad, keeled, the lateral margins
bent upwards, the terminal portion bent sharply upwards and bearing the ''four
leaf clover" appendage characteristic of the genus. Styles robust, rounded and
not angulate, the apical portion of each suddenly constricted.
General color uniform dull brownish yellow (specimen probably having been
at some time in a liquid preservative^. Wings with the disk dull grayish brown,
the anterior field and periphery of the general tint.

INSECTS OF BEULAH, NEW MEXICO. 35
A LIST OF THE INSECTS OF BEULAH, NEW MEXICO.
EDITED BY HENRY SKINNER.
In the summer of 1901 I determined to go to the Rocky Mountain?
on a collecting expedition and vacation, and was influenced to select
Beulah, New Mexico, from the fact that Prof. T. D. A. Cockered
had taken Argynnis nitocris there. The country was represented to
me as interesting from a scenic standpoint and also a good place
entomologically.
Beulah is situated in Sapello canon in the main range of the Rocky
Mountains, about thirty miles north-west of Las Vegas in San Miguel
County, New Mexico. The elevation of Beulah Post Office (Bark-
er's ranch) is about 7,250 feet. My headquarters was at Blake's
ranch, 8,000 feet elevation. The fauna and flora here are those of
the Canadian zone. The Sapello river runs through the canon and
at Beulah is a small but swiftly running creek.
I arrived on the morning of August, the 9th, and left on August,
the 26th, thus having sixteen days collecting. Rain fell every day
but one during my stay. The thunder storms of the rainy season
usually commenced in the afternoon, and unfortunately left every-
thing wet for some time on the mornings following. It was gener-
ally ten A.. M before the vegetation was dry enough to permit fair
collecting. However, by hard work I managed to get a considerable
number of insects of all orders. Coleoptera were comparatively
scarce, as were also the night flying moths, and very few of the latter
were taken at night. The best night catch of moths was made dur-
ing a rain storm. No sugaring was attempted. Vegetation is pro-
lific, and the timber line is well toward the top of the main range
(11,000 feet). During the month of August the nights and morn-
ings are quite cool and fire is necessary for comfort.
When I returned to Philadelphia and mounted the material col-
lected, I turned it over to various specialists for study and determin-
ation, and feel very grateful to the entomological friends who have
so kindly aided me. I am specially indebted to Prof. T. D. A. Cock-
erell, who generously placed in my hands all his valuable records.
In addition to his own collecting he also includes the material cap-
tured by Willmatte Porter (now Mrs. Cockered), and his late son.
Martin D. Cockerel!. This material he had determined by students

of the various orders. I wish to mention the kindness and courtesy
shown me by Col/F. A. Blake and his family, and a]so Mr. Barker.
There are other lists that the student may consult with profit in
conjunction with this. They are are as follows :

f Argynnis nitocris was described from a single male, by Mr. W. H. Edwards in
1874. It was taken in the White Mountains of northeast Arizona. The female
was described by the same author in the Can. Ent. in 1883. A few females have
heen taken in Colorado and Nevada. Strecker described a female from the Rio
Florida, S. W. Colorado, in 1883, under the name aberration nokomis. In 1900
Prof. Cockerell found a variety of the species at Beulah which he named nigro-
coerulea. This species has heen one of the great rarities in collections, and it is
probably due to the fact of its late flight and very local habitat. It was abundant
after the middle of August below Barker's ranch (7200 ft.), but I did not see a
single specimen in the canon above this place. Their headquarters seemed to
be between Barker's saw-mill and Heinlen's ranch. Their flight is swift and the
species is wary, but is readily taken if approached carefully while it is feeding on
the flowers of a tall sunflower which grows rather abundantly at this place in the

canon. Most of the females were taken in a damp meadow near some old build-
ings below the saw-mill. Violets grow in profusion in this meadow. The males
when not feeding on the sunflowers were seen "dipping" over the meadow in
search of the freshly emerged females.
This habit of flight, which I call dipping, seems to be peculiar to the males of
certain species of Argynnis while in search of the females hiding in long meadow
grass. This is the only species in the genus, as far as I have observed, that seems
partial to sunflowers. During my stay I took about one hundred specimens and
could have obtained many more. Mrs. Cockerell succeeded in obtaining eggs of
the species. I have received the variety coerulescens described by Dr. Holland
from Mexican specimens, from the Santa Catalina Mountains in southern Ari-
zona. Nitoeris is a fine species and its varieties are handsome, and doubtless
other forms of the species will be found when the high mountain valleys of the
Southwest are better known. The species is found as late as the middle of Sep-
tember; Dr. Holland's variety having been taken in the Piedras Verdes i7100 to
7300 ft.) in Chihuahua, Mexico, September 15th.

new to New Mexico. In the type the abdomen has ochraceous pub-
escence on first two segments, the rest black. The specimen here
recorded has the pale pubescence on first segment very sparse, the
segment almost bare as though the hair were rubbed off, in fact the
hairs that do exist on the middle of the segment are largely black,
fhe yellowish ones only prominent at the sides of the segment

where they form the ends of a curved band of rather sparce yellow-
hairs, which line the anterior portion of the second abdominal seg
meut. There is a yellow band of hair on the fourth segment and
some yellow hairs on the extreme sides of the fifth segment, fifth and
sixth with black hairs. In the abdominal arrangement of pubes
cence it agrees more with a specimen in the Society's collection
marked "Canada," but that has the ochreous pubescence on first
and second abdominal segments very abundant. The hairs on the
thorax are slightly paler than in the type.

Paiiurgiiiiis bakeri < ' l i ;
Three males, agreeing with the description of bakeri, the sculpture
of the metathorax is variable, the enclosure at best poorly defined,
in two specimens not at all, the metathorax being uniformly rugu-
lose. In one the lower angles of the face adjoining the clypeus
bear a small yellow spot, in another there is a short yellowish line
on anterior tibia?. This species is closely related to P. califomieus
Cress., from which it differs in sculpture, stature and color, bakeri
being black while califomieus is more brownish. In califomieus
the punctuation on dorsulum is sparse and the metathorax has a
smooth spot on each side. Among eight specimens (type and co-
types S ) all but one has the clypeus entirely yellow, the individual
with but a median spot is marked "var." some have a small supra-
clypeal spot and one has well defined lateral face marks.

punctures more distinctly separated, sculpture of cheeks indistinct, clypeus with
large, close deep punctures. Labrum subtruncate anteriorly, concave, shining.
Mesopleurse rugulose. Dorsulum very closely punctured slightly impressed me-
dially and anteriorly, scutellum punctured much the same. Metathorax opaque
finely granularly rugulose. Wings hyaline, with a dark cast, stigma and nervines
dark brown, first recurrent nervure received by the second submarginal cell about
as far beyond the first transverse cubitus as the length of the first abcissa of the
radius, second recurrent nervure received by the second cubital cell, a short dis-
tance before the second transverse cubitus. Base of first abdominal segment
polished with very sparse minute punctures, the segments with the raised half
indistinctly finely sculptured. Entire insect more or less covered with short
whitish to yellowish pubescence.

A male collected by Dr. Skinner has the abdominal segments,
second to the seventh inclusive, a bright orange-red, except for a
narrow lateral and posterior margin of black. Two males collected
by Mr. Henry L. Viereck, June 29, vary somewhat from the typical
form and from the one collected by Dr. Skinner in having the second,
third and fourth and the basal third of the fifth segment in one, and
the fifth and sixth in the other red Two of the three male specimens
in my collection from Bear Creek, Col., collected by Mr. E. J. Oslar,
show the same variation ; the other being typical.
Mr. Viereck also obtained a female at Beulah, which has not been
heretofore described. It closely resembles the male except in the
color of the abdomen. The second segment has a broad basal band
of red and a narrower one separated by about an equal width of
black ; segments three to seven inclusive have a sub-basal red band
about one third the width of the segment; that on the seventh seg-
ment somewhat smaller and interrupted ; the bands do not reach
the lateral margin. Ovipositor dark brown. Length of $ 14
mm., 9 19 ram.

This seems to differ from the typical form in having no lateral
line of red on the thorax.

thickly covered with hair than the dorsal portion of the thorax. Abdomen shin-
ing, steel-blue, sides of the first three segments partly yellowish pollinose, leav-
ing numerous isolated or connected spots of the ground color; along the posterior
margin of the first and anterior margin of the second it extends well towards the
dorsum. Legs black ; the femora somewhat brownish, with a white pollinose
spot at the base of the posterior femora and on the outer side at the base of all
the tibia?. Wings, alula? and squama?, dark brown. Length 21 mm.

BY EDWARD P. VAN DUZEE.
HETEROPTERA.
Homcemus geneifrons Say.
Several examples.
Perillus exaptus Say.
One large specimen. This has a crimson band between the
humeri ; and the anterior edge of the pronotum, the margin of the
scutellum, and the costa narrowly, is fulvous.
< orimelteiia iiiti<lnloi<les Wolff.
One example.
EuscliiMtllS i nihil iim n. sp. — Size and general aspect of servus to which it
is closely related. Head about as in servus with the punctures finer; the lateral
lobes slightly longer than the tylus, depressed, with the edges a little reflexed.
Pronotum more depressed anteriorly, and particularly within the middle of the
lateral margins than in servus, the sides rather deeply sinuated, and crenulated
anterior to the middle ; humeral angles subaeutely rounded ; surface finely punc-
tured, more obscurely so across the middle of the disk, the punctures segregated
toward the lateral margins and forming a blackish patch behind the anterior
angles and several small spots before the callousities, or there may be four black
dots in a square on the anterior middle; median line obscurely la?vigate.
Scutellum more closely punctured, but less so than in servus: the apex much
broader and more rounded. Elytra rather sparsely and finely punctured, espec-
ially on the discal area, the whole surface dotted with little groups of black
punctures. Membrane dark grey, dotted with fuscous, the nervures concolorous.
Connexivum with square blackish spots against the incisures, on which the
punctures are pale. Whole lower surface pale yellow, punctured and flecked
with rufous. Stigmata, and sometimes two punctures behind them, black. Edge
of the abdomen with a conspicuous black dot at each incisure. Legs rufous,
more or less punctured with darker and with about four larger black dots on
each femora beneath ; the spines on the anterior femora very small. Rostrum
as in servus, reaching to the hind coxa?, the tip and a median line beneath black.
Antenna rufus, fifth. joint and apex of the fourth dusky, second and third sub-
equal. Leugth 11-13 mm. Width across the humeri 7-8 mm.
Described from 12 examples taken by Prof. E. D. Ball in Colo-
rado ; and one specimen collected in Beulah, New Mexico, August
17th, by Dr. Henry Skinner. This species is closely related to
servus but may be readily distinguished by the rufous color beneath,
the depressed pronotum, with an obscure longitudinal smooth line,

the more rounded apex of the scutellum, and the finer punctures
over the whole upper surface. The dotting of the elytra is quite
characteristic but perhaps should not be depended upon. Euschistus
conspersus described by Dr. Uhler in 1899, is surely very close to
this species, but he gives the second joint of the antennae in his
species as much shorter than the third, the apex of the scutellum
narrow, bordered with white, and the pleura with uncolored punc-
tures, none of which characters will fit this species at all ; the size
given for conspersus is also a little less and the form more slender.
This interesting addition to our North American fauna is apparently
confined to the Rocky Mountain region.
Alydus scutellatus n. sp. — Small, greyish above, scutellum deep velvety
black, nervures of the membrane anastomosing. Length to tip of membrane 9
mm. Head proportionately a little broader before the antenna-, and the vertex
more convex, with the ocelli placed farther back than in eurinus and consper-
sus; bronze black, with a median longitudinal line above, a more slender abbre-
viated lateral line before and a little above the base of the antenna?, and a short
oblique line behind and beneath the eyes, soiled white or pinkish. Antennae
fuscous, a little paler on the basal half of the first three joints, these, joints sub-
equal in length ; apical joint black, little longer and stouter than in eurinus.
Rostrum reaching to the intermediate coxa?, minutely touched with pale at the
intermediate incisures. Pronotum bronze-black, coarsely punctured, marked on
the posterior lobe with four or six pale vitta?, more or less distinct; a median
longitudinal velvety black line from the collar almost to the base; posterior
margin very narrowly edged with pale around the humeral angles and before
the middle of the scutellum; surface almost flat posteriorly, a little depressed
within the humeral angles. Scutellum deep velvety black, with the tip of its
upturned apex pale. Elytra pale or tinged with pinkish, punctured and irregu-
larly varied with blackish. Membrane bronze-black, becoming paler exteriorly,
the nervures strong, irregular and somewhat reticulated and branched in places.
Beneath shining bronze-black, the propleura coarsely punctured, the calloused
edges of the coxal orifices, a median spot on the second, and the hind edge of the
sixth segment, yellowish or tinged with pink. Genital segment black, polished,
with a large median fulvous spot. Legs black, with the tips of the coxa3, knees
and basal half of the first tarsal joint, pale. Posterior femora more slender than
in any of our other species, with four large spines and a few minute ones beneath
marked near the apex with an obscure pale band. Disk of the tergum rufous
posteriorly. Connexivum with a small pale marginal spot near the base of each
segment.
The claspers of the male are strap shaped and curved almost in a
semi-circle, approximating at their apex which is a little wider and
slightly refiexed at the upper angle. In conspersus the claspers are
narrowed toward their apex and approach at an angle making a
pear-shaped opening. In eurinus they are broader with a smaller

orifice. The whole insect is clothed with minute hairs about as in
conspersus.
Described from two males collected by Dr. Henry Skinner, Aug.
17th, at Beulah, New Mexico. This is the smallest Alydus known
to me. It may be distinguished from conspersus, its nearest ally, by
the undotted membrane, with anastomosing nervures, the more
slender hind femora, with a pale annul us before the apex, and many
of the other characters enumerated above.
C'orizus Iiyaliuiis Falir.
One specimen of the variety viridicatus Uhler.
C'orizus novteboracensis Sign.
One specimen, somewhat mutilated, seems to belong to this
species. I have a slightly paler example taken by Prof. Wickham
at Kalispell, Mont., and a more typical male from British Columbia.
An extension of its range along the Rocky Mountains to New Mex-
ico would not be surprising.
Lygseus turcicus Fabr.
Two examples.
Nysius aiigustatus Uhler.
Several examples.
Lfigyroeoriw balteatus Stal. ?
Seven examples. This species was described from Mexico and
has not before been recorded from the United States. The present
specimens differ from Stal's description in having the posterior lobe
of the pronotuin almost black with four ferruginous spots on the
hind margin, the intermediate of which may be extended anteriorly.
These are also brachypterous, a feature not mentioned by Stal.
♦I iris h Hi 11 is Rent.

Leptopterna dolobrata Linn.
Two examples of the pale form of this widely distributed European
species were doubtless taken about the cultivated fields, in which
situations they occur throughout Colorado and Utah.

Calocoris superbus Uhler.
Five examples.
Resthenia rnbroi ilia Stal.
One example.
Phytocoris interspersus Uhler.
One pale example. This specimen has four brown dots on the
hind edge of the pronotum. The two black dots at the tip of the
scutellum seem to be characteristic of this delicate species.
C'ompsocerocoris annulicoriiis Reut.
Two adults and one larva. These adults are quite distinctly
mottled with darker on the elytra and have a white median line on
the vertex and pronotum, and the third joiut of the antennas want
the pale annulus. Otherwise they do not seem to differ from Reuter's
description.
Poecilocapsus lineatu* Fabr.
Nine specimens. Some of these show the black markings greatly
reduced. In one or two individuals the subcostal vitta is entirely
wanting, the sutural is narrow and interrupted, and the triangular
spots at the base of the pronotum are barely indicated.
Lygus pratensi* Linn.

A pi oilier us crassipes Fabr.?
One female example I have placed here with some doubt. The
pronotum is black with the posterior margin behind the humeral
angles narrowly edged with whitish, the connexivum is black with

a pale spot at each incisure, and the corium is dark sanguineous
with the hind edge and costa narrowly pale.
Coriwcus ferus Linn.
One strongly marked specimen. This widely distributed species
seems to follow cultivation and irrigation throughout the arid re-
gion of the West.
Coriscus sp.
There is one example of another species I have not been able to
locate. This is a difficult genus and sadly needs revision.
Hygrotrechus remigis Say.
Two examples.
Notonecta sp.
One immature example.
HOMOPTERA.
C'ereNH turbida Godg.
Eight male and five female examples.
Thelia univittata Harris.
One male and three females.
Microceiitrus perdita Am. & Serv.
Four examples. I found this species not uncommon in Colorado
on the lower branches of the scrub oaks where they lay close to the
ground.
Aphrophora irrorata Ball.
An interesting species of which there are two specimens in the
lot.
Clastwptera obtusa Osborn.
Five male and four female examples. While collecting in Colo-
rado I took this species only on pine on the mountain sides.
Clastoptera xanthocephala Germ.
Two examples. These are of the black form which I have taken
to be the characteristic type of the species. The color above, espec-
ially on the pronotum, is of an intense shining black ; a transverse
line on the base of the vertex, another near the fore margin of the
pronotum, and two converging lines on the scutellum, are clear

bright yellow. There is also a yellowish vitta on the suture between
the coriurn and clavus. The hyaline spots on the costa and apex of
the elytra are narrow, and there is an . indication of a yellowish
annulus about the gibbous area on the elytra. Face fulvous with a
black disk. Legs yellow, annulated with black. This is a very
different looking insect from the pale .testaceous form described by
Prof. Ball in his synopsis of the genus Clastoptera as xanthocephala.
Although so different in coloring they may represent forms of one
species. The variation which seems to be in color only is perhaps
no greater than we find in Clastoptera proteus Fitch.
Oncometopia costalis Fahr.
Apparently common. Fifteen examples were taken.
Tettigonia hieroglypliica Say.
Thirteen examples.
Helochara communis Fitch.
Two examples.
Gypona inelanota Spanbg.
One immature specimen determined by Prof. E. D. Ball.
ldiocenis lachrymalis Fitch.
One female.
Idiocerus suturalis Fitch.
One female of the form with the maculated elytral suture.
Phlepsius cuinulatus Ball.
Six examples. This stout little species seems to be quite abundant
throughout the mountains of Colorado and the adjacent States.

Beulah, N. M., about 8,000 feet with Lasius niger. This is cer-
tainly a Phenacoccus, having 9-jointed antennae, lateral patches of
spines, and the claws with a small denticle on the inner side. The
presence of the pairs of caudal bristles (as in Halimococcus and
Phcenicoeoccus) is interesting. The insect closely resembles Ripersia
salmonacea, Ckll.

APHIDID.E.
BY T. D. A. COCKERELL.
Siphocoryne pastiiincse (Linne).
Beulah, N. M., July 26, and in vast numbers August 2, on fruit-
ing unibles of Heracleum lanatum.
Winged £: pale dull green; dorsum of head, ruesothorax and scutellum,
shining black; a large square black patch on middle of abdomen, followed by
three, transverse black bars. Legs pale greenish, ends of tarsi black. Stigma dark
brown. Anteunse, nectaries and cauda short. Mesosternum black; a black patch
on under side of abdomen near tip. Young, apple green with black eyes; some
specimens are pink.
The species has not been recorded from America under the above
name, but I believe S. archangelicce Oestlund is a synonym. I
wanted to believe that the celery aphid figured in Bull. 102, Michigan
Agr. Exp. Sta., p. 20, was also Siphocoryne, but while the venation
agrees, the antennae are much too long.
Aphis epilobii, Kalt.
Beulah, N. M., on a flowering head of Epilobium angustifolium ;
extremely abundant, covering the whole surface. Attended by
Fur mica sanguinea.
Winged 9: entirely black, the abdomen shining; anterior legs more or less
pallid ; beak scarcely reaching middle coxae ; antennae shorter than body ; ventral
surface of thorax olive brown to black, of abdomen usually dull dark sage green ;
wings hyaline, stigma blackish or pale. Pupa with wing-pads has a pale brown
bead and thorx, and dark slate abdomen. Apterous form dark slate-color, white-
pruinose; basal two-thirds of antennae, nectaries and legs (except tarsi) whitish
or yellowish-white. Very young vary from slate gray to pale orange, and occa-
sional half-grown examples are brownish orange.
The species is new to America.
Aphis clienopodii Cowen.
Beulah, N. M., August 5, on Chenopodium album, curling the
leaves.
Winged 9 : head and thorax black, abdomen green without spots. Opterous
form light green, pulverulent; eyes black (reddish in younger ones) ; cauda quite
long; nectaries short, slender; legs pale yellowish, tarsi blackish. The antenna]
joints of the winged form measure in (i. (3.) 320, (4.) 160, (5.) 160, (6a.) 120, (6b.)
215.
Aphis veralri Cowen.
Beula, N. M., July 27, etc., abundant on leaves of Veratrvm.
Apterous form black ; basal half of antenna? (except extreme base) ; anterior
femora and all the tibise dull white.
INSECTS OF BEULAH, NEW MEXICO. 115
Apliis valeriane Cowen.
Beulah, N. M., July 27, on Valeriana ; very abundant.
Apterous form slaty black, including leys, etc.; more or less distinct whitish
spots on back. One specimen of an olive-black Necttirophora was found with
them.
Apliis rociada* n. sp.
Rociada, N. M., August 8 ; very numerous on leaves and stems
of Delphinium sapellonis.
Apterous 9: small, broad and swollen, very shiny, bright orange-scarlet to
dark red. No obvious cauda ; nectaries very short, but larger than broad, black
at ends; bead blackish ; antennae blackish, third joint paler; legs brown. Mounted
examples are pale ferruginous, slightly over 1A mm. long; nectaries about 150/'.
long, slightly bulging toward the bases. Antennal joints in/'.; (4.) 200, (5) 170.
(6a.) 80, (6b.) 340. Younger example shows (1) 70, (2.) 60, (3.) 320, (4.) 130, (5a.)
80, (5b.) 290.
A very distinct and beautiful species; I brought some alive from
Rociada,* and established a colony at Beulah.
Aphis atroiiitens n. sp.
Rociada, N. M., August 10; abundant on Vieia aff. pulchella.
Winged f: shining black; wings hyaline, nervures and stigma colorless or
barely tinged with yellow; legs pale greenish ; nectaries long ; beak hardly reach-
ing middle coxse ; cauda rather long, slender. Measurements in /'. : nectaries, 300;
Cauda, 100; anterior tarsus, 130; antennal joints (3.) 280 or more, (4.) 250-280,
(5.) 240-260, (6.) 140. (6b.) 230. Joint 3 witb few sensoria, 4 with none. (In A.
epilobii, a black species found in the same region, joints 3 and 4 are crowded with
large sensoria.)
Apterous form plump, gray-black, shining; legs very pale yellowish, the tarsi,
end of tibiae, and apical two-fifths of hind femora, black ; antennae with joints 3
and 4 whitish ; nectaries black.
Young, dark gray. A. atroiiitens reminds one of the English A.
fabte, which is said to be identical with A. rumieis. The characters
of the antennae readily distinguish J., atronitens from A. rumieis.
In mounted specimens the bicoloration of the legs is conspicuous.
Mjzus phenax n. sp.
Beulah, X. M. ; very abundant on flowering racemes of Hamulus
lupulus var. neomexicanus, first found by my wife July 28. Attended
by Formica.
Winged $?: body about 2 mm., wings about 3 mm.; mounted specimens (in
balsam) are dark brown, with dark red eyes, but in life the colors are as follows:
head and thorax black ; abdomen dull green, witb lateral black spots, and dorsum
* Rociada is just over the hill from Beulah.

marbled with black ; nectaries black pointed inwards ; wings hyaline, stigma pale
gray; antennae black; beak falling a little short of middle coxae; anterior legs
pale ochreous, with black knees and tarsi ; four hind legs with femora and tarsi
black, tibia pale ochreous. Measurements in [i. : nectaries 300 long, 70 broad ;
cauda 170; marginal cell with substigmatal portion 300; poststigmatal 500; an-
tennal joints, (3.) 480, (4.) 260, (5.) 210, (6a.) 100, (6b.) 300. Joint 3 crowded
with sensoria, 25 or more ; 4 without sensoria.
Apterous form stout, dull green (mounted specimens dark brown), clouded ob-
scurely with a darker blue green; nectaries black, directed outwards; legs
yellowish with black tarsi ; hind femora with distal half clouded with blackish.
The sides of the back exhibit some very small black spots. Antennae with the basal
half mostly pale yellowish, apical half black. Lateral tubercles as described in
M. neomexicanus. No capitate hairs.
When I first saw this, I thought I had Phorodon, but none of the
specimens can possibly be referred to that genus. The insect is a
Myzus closely related to M. neomexicanus. It has a strong super-
ficial resemblance to Aphis gossypii, which Pergande records from
Hiimulus, but it can easily be distinguished by the numerous and
crowded sensoria on the third antennal joint, A. gossypii having
only five to seven.

DESCRIPTIONS OF NEW A1VT-EIKE AND MYRME-
COPHILOUS HYMENOPTERA.
BY CHARLES THOMAS BRUES.
Laboratory of the U. S. Fish Commission, Woods Hole, Mass Sept. 6, 1902.
The present descriptions and notes are based upon Hymenoptera
collected while searching for ants and myrniecophiles. As many
insects not associated with ants are found at such times, only those
are included which are evidently myrmecophilous or which re-
semble ants in form and habitus. All of the ten new species belong
either to the Proctotrypoidea or Ichneumonidse, two groups rich in
myrmecophilous and ant like species.

IVzomachus Birkiiiani sp. nov.
Female. — Length 3.5 mm. — Slender, yellowish ferruginous, except a piceous
spot at the base of the abdominal petiole, narrow piceous band at base of third
abdominal segment, black tips of mandibles and infuscated apical joints of an-
tennae. Antennae stout, 19-jointed, somewhat thickened toward the apex, almost
as long as the body, their joints shorter than usual, tlie eighth flagellar joint being
no longer than wide. The joints annulate with black from third joint, the rings
becoming wider and the joints wider apically. Ocelli equidistant, the posterior
ones about equidistant from one another and the eyes, each ocellus surrounded
by a very small elongate black spot. Thorax more sharply constricted than usual
between meso- and metathorax. Mesonotum not impressed, its lateral dentiform
processes distinct, the dorsum evenly but not very convex and much longer than
the metathorax. Metathorax rather sharply declivous behind, more sharply con-
vex anteriorly, its posterior face very finely rugose, separated from the dorsum
by a fine raised line which is interrupted medially. Abdominal petiole rather
long, its lateral teeth large and distinct. Abdomen more shining than the head
and thorax, ovate, first and second segments yellow ferruginous; a piceous band
at the base of the third ; following segments darker. Legs yellowish ferruginous.
Ovipositor about one aud one-half times as long as the abdominal pedicel.
A female specimen collected at Fedor, Lee County, Texas, by
Rev. G. Birkman, on April 1, 1901.
This species comes near to alternatus Cress., and like it has the
antennal joints unusually short. It differs from the latter in having
a long ovipositor which extends beyond the tip of the abdomen for
a distance considerably greater than the length of the petiole of the
abdomen.
I'czomaelms maculi<-olli* sp. nov.
Female. — Length 2.5 mm. Black, with ferruginous markings. Head black,
not shining; face below antenna? ferruginous except for a longitudinal stripe
below each antennae. Mandibles reddish black at the bidentate tips. Palpi fus-
cous. Antennae pale ferruginous, with dark incisures at the joints and blackened
on apical fourth, 19-jointed. Cheeks fuscous below. Thorax black, not shining ;
collar rufous on the sides, mesonotum with a ferruginous V-shaped spot pointing
anteriorly, a small ferruginous spot each side of the apex of the V. Metathorax
with two ferruginous dorsal spots. Posterior lobe of the thorax much more
strongly and sharply convex than the anterior lobe and about as long. Posterior
face of metathorax bordered by a sharp carina, finely rugose; thorax elsewhere
delicately punctate. Scutellum absent. Abdomen piceous black, subclavate; first
segment rather short and broad and gradually dilated posteriorly ; piceous-brown

in front and yellowish behind. Second and following segments shining piceons,
with a few short white hairs, second very narowly reddish posteriorly. Oviposi-
tor exceeding tip a little more than length of first abdominal segment. Legs
luteous, more or less darkened on the coxse, femora and tibiae.
Described from a female specimen collected in nest of Leptothorax
longispinosus Roger. P. maculicollis is readily recognized by its
small size and by the ferruginous markings on the thorax. It evi-
dently mimics the ant with which it lives, resembling it greatly in
size, color and general habitus.
I have also a single $ and 9 collected at AVoods Hole, Mass.,
which belong perhaps to this species. The thoracic spots are very
faint in the 9 > which has 20-jointed antennae and more distinct
tubercles on the petiole than P. maculicollis. The apterous male
has also 20-jointed antenna and a narrow scarcely dilated black
petiole. The legs are slightly darker than in the 9 .
Fezomaclius texauiiM Cress.
This species occurs at Austin, Texas, associated with the ant So
lenopsis geminata Fabr. A male specimen collected by Dr. William
M. Wheeler in a nest of the same ant at Corpus Christi, Texas, proves
to be wingless. It diners from the female in having the antennae
almost as long as the body ; the head entirely honey yellow ; scutel-
lum very distinct (it is very faintly separated in the female). The
pedicel and whole abdomen, as well is much elongated. The anten-
nae are 22-jointed ; they are 21-jointed in the female.
Var. nigriventris. — Several females from Austin Texas, differ from
the typical form in having the head and thorax dark ferruginous,
and the whole abdomen behind the petiole shining black.
Pezomachu* angularis sp. nov.
Female. — Length 2.75 mm. Small, slender, black. Tip of petiole and abdomen
pale. Head shining, rather densely and finely punctured ; black above, deep
yellow in front below the antenna; and below on the cheeks behind. Mandibles
and palpi luteous, the former black at the tips. Antennae slightly longer than
the body, 22-jointed, yellowish at base and infuscated apically. Thorax slender,
the anterior and posterier lobes very nearly equal, the posterior one more strongly
arched ; fuscous or piceous brown, lighter on the sides of the pro- and mesothorax.
Mesonotum finely punctured, not sulcate. Metathorax more coarsely punctured,
especially behind, without any keels. Abdominal petiole with its lateral tubercles
very prominent, behind which it is constricted and then widens out to the apex,
where it is no wider than at the tubercles. Petiole piceous, paler at base and
with a luteous band at apex. Abdomen elongate oval, rather slender, scarcely
wider than the head; shining and sparsely finely sericeous pubescent. Second to
AMERICAN HYMENOPTERA. 123
fifth segments piceous black, apical segments pale yellowish. Legs dark fuscous,
trochanters, sutures and apices of tarsi paler. Ovipositor as long as first and
second segments together, ferruginous.
Described from one female specimen collected at Austin, Texas,
May, 1902.
This species resembles Pettitii, but is smaller and has a differently
formed abdominal petiole.
Pezomachus crassulus sp. nov.
Female. — Length 4.5 mm. Large and stout, ferruginous, slightly infuscated on
the abdomen. Head ferruginous, slightly darker on the occiput, rather finely
punctate and not at all shining, very sparsely silvery pruinose. Face, consider-
ably produced just at the base of the antennae. Mandibles deep yellow, black at
the tips; palpi rufous. Antenna3 short, stout (broken), thickened toward the
tips and probably reaching about to the base of the second abdominal segment.
Rufous at base, paler and with dusky incisures toward the tip; with at least 23
joints. Thorax short and stout, less strongly bilobed than usual, the lobes of
equal length, ferruginous. Mesonotum sculptured like the head. Metanotum
indistinctly areolated in front, distinctly so behind. Petiole gradually widened
out towards its apex, the lateral tubercles not prominent; longitudinally acieu-
lated above and sparsely covered with sericeous pubesence. Abdomen very
shining, sparsely punctulate and thinly pubescent; broadly oval; ferruginous
except at the base of the second and third segments where it is slightly infus-
cated. Legs dark ferruginous throughout.
Described from a single female collected under a stone at Austin,
Texas, daring April, 1902.
This tine species resembles unicolor Cress, in color, but is readily
separated by the characters given in the table, and by its opaque
head and thorax.
I'ezomaclius Wlioeleri sp. nov.
Female. — Length 3.5 mm. Rather stout, black, with reddish markings. Head
large, black, finely punctured, mandibles black ; palpi testaceous, cheeks smooth
and very shining, face not produced at the base of the antenna?. Antenna? pice-
ous, paler towards base, especially below ; 20-jointed. Thorax strongly bilobed ;
anterior lobe dark ferruginous, with darker humeral marks; posterior one black :
slightly ferruginous on the anterior upper face. Posterior lobe longer and more
convex. Mesonotum slightly longitudinally impressed medially, metanotum
smooth, very finely shagreened, with a delicate carina laterally, which is inter-
rupted above. Abdominal petiole very short and broad, gradually dilated to the
apex, dark rufous. Its lateral tubercles not at all prominent; abdomen very
broad behind the petiole, regularly oval ; shining black, except for the narrow
dark yellow border of the second segment and a faint trace of narrower light
borders on the third and fourth segments. Ovipositor exceeding the apex of the
abdomen by the length of the petiole. Its sheaths pale at base and piceous at
tips. Legs piceous, the trochanters, knees, anterior tibise at tip, and all the tarsi
more or less rufo testaceous.

Ateleopterus virgiiiiensis Ashm.
I have two wingless females of this species collected at Round
Rock, Texas; the species was originally described from Virginia.
Mesitius mj rmecophilus sp. nov.
Female. — Length 3.2 mm. Black, shining, with sparse pale hairs; antenna; and
legs brown ; wings slightly infuscated. Head scarcely longer than wide, shining
black, with widely separated, but very distinct punctures; sparsely covered with
rather long whitish hairs. Antenna? 13-jointed, reaching to the tegulse, dark
ferruginous at base, fuscous at tip. Scape short and stout, scarcely equalling one-
half the greatest width of the head; pedicel more slender, but scarcely longer
than the first flagellu in joint. Following three joints quadrate, beyond which
they are very slightly longer than wide; apical joint slender, twice as long as
wide. Palpi and mandibles ferruginous, the latter dark at extreme tip. Prono-
tum sparsely and more finely punctured than the head, shining and with short
pale hairs, considerably longer than the mesonotum and scutellum taken together ;
tegulaa ferruginous. Mesonotum impunctate, with two fine longitudinal grooves,
which enlarge posteriorly and meet the two large foveas at the base of the scu-
tellum. Metanotum with a lateral and a median fine raised line and a fainter
one between these anteriorly which fades out behind ; delicately reticulate. Pos-
terior face with median and lateral raised lines very sharp, separated from the
metanotum by a similar line; very finely transversely rugoso-aciculate. Abdo-
men polished black, impunctured, pale hairy on posterior half. Sixth segment
ferruginous at tip. Wings hyaline, basal veins yellow ; stigma ami radius fus-
cous. Second basal cell without a backwardly directed vein. Marginal cell long
and widely open at tip. Legs rufopiceous.
Described from a 9 specimen collected in a nest of Eciton caecum
at Austin, Texas.
AMERICAN HYMENOPTERA. 125
The present species is a typical representative of the genus, and
comes nearest to M. nigropilosus Ashni. in form, but has pale pubes-
cence and a longer pronotum. It differs from the other species in
the form of the head and antennae.
Gonatopus peculiaris sp. nov.
Female. — Length 2.75-3 mm. Polished black, except the greater part of head,
sutures of legs and base of antennae, which are reddish or yellow. Head dis-
tinctly less than- twice as wide as lotig, ferruginous, except a transverse black
band between the eyes on the vertex. Mandibles except tips and antenna] scape
luteous; pedicel and sometimes base of first flagellar joint yellow; remainder of
antennas black. Mesonotum smooth, shining, evenly arched above and not emar-
ginate when seen in profile. Metathorax transversely striated before and behind,
smooth at the middle. Abdomen polished black. Legs varying from piceous to
ferruginous, the coxa? and sutures paler, often luteous. Entire insect very
sparsely white pubescent.
Described from four £ specimens collected near Austin, Texas,
in the early spring. They were seen actively running about on the
ground, some near the bank of a stream and the others on dry hill-
sides. I have also collected G. bicolor Ashm. at Granite Mt., Tex.,
under stones, and G. contortulus Patton upon low herbage, near
Woods Hole, Mass., in the same surroundings as the specimens de-
scribed by Dr. Patton.
This interesting species resembles G. contortulus Patton in form
and color, but differs from it as well as from the other species of
Gonatopus in lacking the V-shaped emargination upon the meso-
notum.
I<li*is nigricoriiis sp. nov.
Male. — Length 2.5 mm. Polished black, legs and antennal scape basally
rufous; sparsely covered with pale pubescence. Head shining, very faintly sha-
greened. Eyes pubescent, lateral ocelli remote from the eye ; mandibles rufous.
Antennae black, except the base of the slender scape, which is rufous; pedicel
very small, globular; first flagellar joint large, one and one-half times as long as
broad, following joints moniliform, slightly smaller than the first; apical joint
longer, obtusely pointed. Thorax very sparsely and finely, but sharply punc-
tate; mesonotal furrows deep posteriorly, fading out anteriorly. Pleura' coarsely
punctured in front, polished behind. Scutellum with a punctate frenum and a
similar row of punctures along its anterior margin. Metathorax finely rugose,
its lateral teeth small and acute. First two abdominal segments longitudinally
striate, abdomen elsewhere smooth and shining, rather closely pale pubescent.
Legs varying from brown to deep yellow or rufous. Wings hyaline, fringed ;
basal vein not very distinct, the marginal about three times as long as thick,
postmargiual equal to marginal ; stigmal twice as long and knobbed at tip.

Described from three % specimens, bred in an artificial nest from
a mixed colony of Myrmica and Leptothorax at Colebrook, Conn.,
August, 1901.
Caloteleia Marlaltii Asfam.
I have numerous specimens of this widely distributed species
which were bred by Dr. Win, M. Wheeler in a mixed nest of Myr
mice and Leptothorax at Colebrook, Conn., August 10, 1901, as well
as specimens from Woods Hole, Mass.
All of the males have the abdomen pale at the base, and the third
abdominal segment smooth, otherwise they agree well with the de-
scription of this species.
Hemilexodes ambigua sp. nov.
Female. — Length 2.5 mm. Black shining, legs and antennas, except apex,
rufous. Head sparsely pale pilose ; mandibles entirely rufous. Antennal scape
reaching about to the posterior ocelli, pedicel stouter than first flagellar joint, but
of equal length. Second flagellar joint scarcely more than half as long as the
first, then the joints become slightly shorter to the fifth which is submoniliform ;
following joints forming a loosely articulated, 6-jointed spindle-shaped club. The
apical joint more slender than penultimate, but longer. Mesonotum sparsely
pale hairy, with two distinct furrows. Scutellar fovea deep and broad, its sur-
face longitudinally fluted. Metathorax wooly, coarsely sculptured. Petiole
about two and one-half times as long as thick, finely longitudinally striated.
Abdomen very shining, black, the petiole below and the base of the second ven-
tral segment sometimes yellowish or rufous. Second segment twice as long as
the remaining segments ; the abdomen obliquely subtruncate at the apex. Legs
yellowish or rufous. Wings strongly fringed, ouly a slight indication of an emar-
gination at the apex. Stigmal vein about two times as long as the very short
marginal vein. Post marginal vein about half as long as the stigmal.
Described from two female specimens, collected in a nest of Ste-
namma fulvum var. piceum, at Colebrook, Conn., where it, no doubt,
lives parasitically upon myrmecophilous dipterous larva?.
I have been doubtful whether this species belongs more properly
to Hemilexis Forst, or to Hemilexodes Ashm., as it presents charac
ters of each, and again departs somewhat from both in the form of
the antenna? and venation.
AUXOP.EDEUTES gen. nov. (see Plate I).
Head orbicular, much produced in front to form a sort of shelf at
the base of which the antenna? are inserted. Seen from the side the
projection is triangular, with a horizontal upper surface. Antenna?
12-jointed, clavate, the last two joints much enlarged, the penulti
mate the longest ; scape rather short, equal to the last two flagellar

joints, pedicel as long as the first and second joints of the flagellum.
Mandibles bidentate; maxillary palpi 3-jointed, labial 2- (possibly
one) jointed. Head narrowed in front of the eyes, the antennal
projection about twice as wide as long, sharply rounded on the cor-
ners. Eyes greatly reduced, much smaller than the last joint of the
antennae and with few ommatidia. Ocelli large, prominent and
arranged in an equilateral triangle upon the vertex, enclosing a
space about equivalent to the eye. Thorax quadrate, slightly pro
duced at posterior angles ; prothorax nearly half as long as wide,
truncate in front rounded behind ; mesonotum narrower than pro-
notum, about three times as wide as long. Wings wholly absent.
Scutellum trapezoidal, rounded on the posterior angles; metathorax
deeply emarginate in the center, forming two rather acute back-
wardly directed teeth. Abdominal petiole short. Abdomen some-
what shorter than the head and thorax ; basal segment twice as
long as the remainder of the abdomen, broadly emarginate at the
base, widest just behind the middle. Third and fourth segments
about equal, short; last longer. Legs short and stout; femora,
especially the four posterior ones, considerably swollen, spur of an-
terior tibiae stout and bifid at the tip ; those of the other legs not
well developed.
Auxopaedeutes <*o<lalis sp. nov.
Female. — Length 1.25 mm. Fuscous, head piceous. antennae and legs ferrugi-
nous. Body quite hairy, the hairs longest and thickest on the antennae and the
posterior part of the abdomen. Head and thorax smooth and impunctured.
Abdomen with a large deep semi-circular depression at base, sharply bounded in
frout by the raised anterior margin of the second segment, and rounded behind,
almost as wide as the base of the abdomen. First segment obliquely striate at
its anterior lateral corners, the abdomen elsewhere smooth and convex.
Described from a female specimen collected by Dr. Win. M.
Wheeler on the banks of Bull Creek, Travis Co., Texas. It was
found in a nest of Solenopais molesta, and is undoubtedly a true
myrmecophile of this minute ant.
The form of the antennae recall somewhat those of Solenopsia
Wasmann, but the insect is otherwise quite different and I have not
been able to determine its systematic position with any degree of
assurance, placing it in the Diapriida?, although it resembles mem
hers of the Belytidse in having a large pronotum, The antennae
resemble those of the Diapriidae in having 12 joints. The number
of antennal joints in ant-nest inhabiting forms tends to be unusual,

however, and the antennae often resemble greatly those of the host
ant ; as is seen in this case to a remarkable degree. For this reason
the form of the antennae may not be so valuable for classification as
other characters.
The general habitus of this form is like that of Solenopsia imita-
trix Wasmann, a peculiar proctotrupid which occurs in the nests of
Solenopsis fugax in Europe, and it is interesting to note the occur-
rence of this somewhat similar form with our North American Sole-
nopsis molesta, which resembles S. fugax in habits. It is apparently
the first myrmecophile which has been found living with this species
of Solenopsis, which is itself a facultative myrmecophile of other
species of ants.

Allied to A. percheron (Guerin) from Cayenne and St. John,
West Indies, but differing in the small exposed portion of the wings,
the greater size and the entire absence of ochraceous coloration from
the insect, the general tint being dull blackish brown.
Size medium ; body moderately depressed, subfusiform. Head cordiform, an-
tennae moniliform, 15-16 jointed. Pronotum subquadrate, the anterior and lateral
margins straight, the posterior rotundate; centrally with a longitudinal depres-
sion. Elytra rather elongate, posteriorly subtruncate, the surface slightly scab-
rous. Wings projecting beyond the elytra as slight truncate plates. Abdomen
considerably wider than the width across the elytra, the lateral folds hut slightly
developed ; aual segment transverse with a central longitudinal sulcus; pygidium
small ; forceps straight with the apex falcate, quadrate in section at the base,
inner margin with blunt denticules.
General color deep blackish brown, becoming fuscous on the lower portions of
the limbs. Antennae with two joints (12-13) ochraceous.

Family PHASMID^E.
liii in pon iti> purtoriceiisiK n. sp.
Type : 9 ; Fajardo, Porto Rico. February, 1899. Collected by

Apparently a member of this genus, but not closely related to L.
guerini (Saussure) the type. It differs in the smaller size, the granu-
late head and thorax, and the differently shaped apex of the abdo-
men.
Form thick and heavily built. Head somewhat flattened, the region between
the antennal bases with an elevated transverse ridge, the basioccipital region with
several low tubercles; dorsal joint of the antennae flattened, the upper surface
undulate. Pronotum almost quadrate, the lateral margins carinate and spined,
centrally with two longitudinal rows of tubercles of three each. Mesonotum about
three times as long as the pronotum, with a longitudinal median carina, the sur-
face tuberculate. Metanotum with the median segment slightly shorter than
the mesonotum, posteriorly expanding. Abdomen slightly tapering, the superior
terminal plate transverse, the posterior margin rounded. Femora very short,
the median pair of limbs equalling the metanotum and median segment in length,
the posterior pair of limbs reaching the apex of the second abdominal segment.
Tibiae shorter than their respective femora. Tarsus with the three basal joints
subequal.
General color dull yellowish green, the antennae with the apical portions of the
large segments bearing a more or less distinct blackish blotch.

A REVISION of the NEARCTIC CHRYSOPIDjE.
BY NATHAN BANKS.
Every entomologist knows Chrysopa ; for there are few regions in
the world where insects abound unrepresented by Chrysopa, or some
allied genus. Throughout our country Chrysopa is represented in
every locality by several species; and everywhere there is at least
one species which may be reckoned among the " common insects."
The delicate green color, the beautiful golden eyes, and, above all,
the peculiar odor of certain species have made Chrysopa familiar to
every collector of insects.
The family Chrysopidse is distinguishable from the other families
of Neuroptera by the following characters:
Mouth not rostrated, no anal space to the hind wings; anterior
legs simple (not raptatorial) ; wings bare (not powdered); antenna'
setiform ; costal space of anterior wing is narrow at base, no recur-
rent vein, transverse veinlets in gradate series. The family is
closely related both in structure and in larval habits with the Hem-
erobiiihe, but a colorational character will always separate them ; the
Chrysopidse are usually mostly green, while the Hemerobiidae arc
never green, but more or less brown. There are various structural
characters which separate the two families. The pronotum in Chrys-
opidse is usually as long or longer than broad, in the Hemerobiidse
it is plainly broader than long. The wings of the Chrysopidse have
many more cross-veins than in the Hemerobiidse; the result is that
most of the cells in a Chrysopid wing are rarely more than twice as
long as broad, while in the Hemerobiid wing the cells are three
times and usually four to six times as long as broad. In the
Chrysopidse there is but one radial sector which is connected back
to radius by at least six cross-veins. In the Hemerobiidse there are
usually several radial sectors, and the last is connected back to the
radius by only one to three cross-veins. In the Chrysopidse the
radial sector of the hind wing is united for some distance to the
median vein ; this does not obtain in the Hemerobiidse.
The Chrysopidse are insects of rather small size with comparatively
large wings. At rest, the wings are held roof like over the body,
and the antennae are extended outward and forward. Their flight

is never rapid, and usually slow and somewhat irregular. They fly
little during day time, and not far even when disturbed. At twilight
and in the early evening their flight is more extended, and they are
then at their best. Several species are attracted to lights. The
females appear to generally deposit their eggs in the afternoon or
evening. Pairing, as far as I have observed, takes place in the day-
time ; the sexes are attached end to end. There are no secondary
sexual characters, save in the genus Meleoma, where the male has a
protuberance between the bases of the antennae.
The odor, so characteristic of some of the commoner species of
Chrysopa, is not (as has been noticed by several writers) found in all
of the species. C. ^-punctata is the most common of the inodorous
species, ('. oculata the most common of the odorous ones. The cib
arian structures are quite well developed ; the mandibles are short
and stout; the maxillae large, and with five jointed palpi ; the labial
palpi three -join ted. Yet, so far as I am aware, the adult insect takes
no nourishment. However, they probably live for a week or more.
When they die, their frail bodies must soon disappear, as I have
never found a dead specimen.
The genital organs in nearly all of our species are withdrawn in
the last segments of the abdomen ; they are rather soft and probably
shrink in drying. They have been used in the separation of some
European forms, but in the few closely allied forms that I have ex-
amined, they are not useful. The tarsi terminate in two claws, sim-
ilar in character in all of our species.
Chrysopa has long been familiar to entomologists on account of
its remarkable larval habits. They pass the winter usually as pupa',
but at least one species, Chrysopa plorabunda, hibernates in the
adult state. Flies of this species have been found in hedges and
heaps of dry leaves during January, February and March. The
hibernating pupa? hatch, according to the species, from March to
June. The flies mate as soon as possible, and then the females pro-
ceed to attach their curious eggs in favorable situations. The egg is
elliptical in shape and attached at one end to a long slender pedicel,
whose base is expanded and attached to the leaf or twig. Usually
there is but one egg to each stalk ; but I have found in July a single
stalk on the bark of oak trees, which bore at its summit a cluster of
ten or fifteen eggs. I did not succeed in rearing the larvse. At
least one European species has a similar habit. In some species the
AMERICAN NEUROPTERA. 139
eggs are laid in groups of from eight to thirty (C. oculata), in others
the eggs occur singly ( C. rufilabris). In the latter class the pedicel
is often shorter than in the former group. In many cases the eggs
are laid in proximity to colonies of plant-lice, upon which the larva1
are destined to feed. Sometimes, however, the larvae are obliged to
search for food.
At the top of each egg is a micropyle — a cup shaped piece pro
jecting above the surface, with a minute central pore. The top of
the egg is irregularly reticulate ; the base is more pointed than the
top. The egg in a day or so becomes darker, and cracks across the
top and partly down one side. Through this slit the larva crawls
out. t is very bristly, has a big head, and a tapering body. The
jaws are very large, the antennae long and curved, and the palpi
broad and project out in front. -The legs are slender, and each
tipped with two claws and a longer median sucker. The larva of
each species is characteristic, though larvae of closely allied forms
differ hut little.
The larva crawls down the pedicel to the leaf, and soon moults.
Fitch has recorded that in some species the first food of the larva
was eggs of other insects, after which the larva attacked plant lice.
In other species, however, the larvae do attack plantdice for their
first meal, and are not as timid as Dr. Fitch records of the larva he
observed. As the larva grows in size it becomes more fusiform in
shape, and in many species each segment develops a lateral protuber-
ance bearing a bunch of bristles. The color becomes darker and
often spotted ; the larvae of the few species known to me being marked
in a different manner. The question of the larval moults is one of
peculiar interest. The new born larva soon moults as is readily ob-
servable ; but from this time till it moults within the cocoon most
authors have observed no moulting. Fitch and Schneider record
that they have not seen a moult, and I have watched in vain. Vine
describes one moult about midway in larval life.
The larvae of some species cover themselves with a pile of debris,
made up of the skins of their victims. This scalp-carrying habit is
also found in the larvae of some Hemerobiids. It is a protection ;
but some species that do not have it are extremely numerous and
appear moderately free from parasites. In travelling about on the
leaf or bark the larva walks in a restless, interrupted way, turning

the head from side to side, and keeping the palpi in motion. The
rail is often used to hold on to some spot, but when not in use is often
carried turned to one side.
These voracious little larvae are known as "aphis-lions;" their
principal food being aphids. However, they will feed on almost any
soft insect, and even upon each other. It seizes the aphid with a
quick movement of the jaws and rapidly sucks the unfortunate vic-
tim dry, often turning it around in order to extract all the juices.
In this manner they destroy a great number of plant-lice in a day.
The innumerable hosts of aphids with their remarkable fecundity
are no match for the ravenous appetite of these Chrysopa larvse, and
in a few days plants badly infested with "green fly" are clean
again. Their useful habits have been commented upon by almost
every economic entomologist ; no* only in the destruction of plant
lice, but as attacking the pear-tree Psylla, scale insects, the chinch-
bug, elm-leaf beetle and other pests.
The length of the larval life is from one to three weeks. AY lien
a proper size is reached the larva rests for a time and then proceeds
to spin the cocoon. This may be placed almost anywhere, sometimes
in a crevice of the bark or a fold in the leaf, but quite as often they
are fully exposed to view. The larva, which is now fusiform in
shape, spins around itself threads which are drawn tighter and
tighter till the larva is curled upon itself as closely as is possible.
The spinning continues and results in a practically spherical cocoon,
white or yellow7 in color. Some cocoons are more elliptical than
others.
The silk glands open near the end of the abdomen, and they emit
a single smooth thread.
After a period of about ten days the pupa cuts off a circular lid
from the cocoon and crawls almost or completely out. The mandibles
of the pupa are short, stout and sharp-pointed, enabling the creature
to cut through its tough cocoon. In a few minutes its back bursts
along the median line and from it gradually issues the adult fly ; at
first pale and weak, but in the course of an hour or so assumes its
full coloration and development.
Shinier has noted that in a larva that had but four legs, the adult
fly from it had all six legs fully developed. Since the Chrysopid
larva lives exposed it is not strange that they are attacked by vari-
ous parasites. The Chalcidids, Perilampus hyalinus, Chrysopophn-
AMERICAN NEUROPTERA. 141
gus compressicornis, Syntomosphyrum orgyice, Aphycus chrysopce, and
all the species of Isodromus issue from the cocoon. Two Ichneumons,
Otaeustes chrysopce and 0. atriceps have also been bred from cocoons.
A Proctotrypid, Telenomus chrysopce, has been bred from the eggs.
Historical.
Several of our early entomologists recognized that we had more
than one species of Chrysopa, but failed to distinguish them from
the European species. Thomas Say, the first in this, as in many
groups, described Chrysopa oculata in 1839. About the same time
Burnieister issued his " Handbuch " in which live species are de-
scribed from our country, one of which is considered identical with
Say's species. Nothing was published for a number of years, until
in quick succession appeared the works of Schneider (1851), Walker
(1853), and Fitch (1855). Schneider's work is a monograph of the
species of the world. He recognized all of Burmeister's species and
added two new ones. Walker's " Catalogue " contained three new
species from the United States. Fitch did not recognize any of the
previously described species, but described all the forms known to
him (twenty-three in number) as new. Probably he was unaware
of Schneider's and Walker's works. About twelve of his species
fall as synonyms.
Hagen in his "Synopsis of the Neuroptera of North America"
(1861) added four species. Shimer in 1862 described one species,
since shown to be identical with one of Fitch's. In 1869 McLach-
lan described a handsome species from Texas.
In 1890 Mr. Coquillett, in the Report of the State Board of Hor-
ticulture of California, described a new species — C. californica. In
1<S'.)2 the present writer described a Nothochrysa, and since then has
added nine other species. In 1894 Mr. Mac Gillivray described two
species of Nothochrysa ; and in 1901 Mr. McClendon described a
new species from Texas. Thus up to date Ave have fifty-five names
for the Chrysopidse of the United States, proposed by twelve persons.
Classification.
For a long time the genus Chrysopa covered all the forms.
Gradually it has been split up, and in this paper our species are
distributed in six genera. Two of these are new. Most of the

genera are very well separated, but Leucochrysa is very close to the
nigricomis section of Chrysopa. These six genera may be separated
by the following table :
1. Third cubital cell divided longitudinally into two sub-equal parts 2.
Third cubital cell divided obliquely into two very unequal parts 3.
2. Veinlets on outer and posterior margins of wings forked ; color green.
Allochrysa.
Veinlets on outer and posterior margins of wings mostly simple ; color dark.
Nothochrysa.
3. Gradate series in fore wings of but three or four veinlets; in hind wings but
one series of gradate veinlets Eremochrysa.
Gradate series of fore wings of more than four veinlets, rarely with but one
series in hind wings 4.
4. Basal joints of antennae widely separated and rather slender; in male with a
horn between them Meleom a.
Basal joints of antennas quite close together; no horn in male. 5.
5. Antenna? much longer than wings; pterostigma with a brown dot.
Leucochrysa.
Antennae shorter, or but little longer than wings; pterostigma without brown
dot. Chrysopa.
NOTHOCHRYSA McLach.
Similar to Chrysopa; the third cubital cell divided subequally as
in Allochrysa, but differing from both of these genera in having the
veinlets on the posterior and outer margins of wings not forked.
The third cubital cell has but one branch to the hind margin, while
in all our other genera there are normally two. The uniform dark
venation and the generally dark color also distinguish this genus
from all our other species. Type N. fulviceps.
Nolhochrysacaliforuica Banks. — Head yellowish ; antennal bases sur-
rounded with black which extends upward on vertex in three lines, one each side
near the eye, and one median, enlarged at tip on top of vertex. Antenna- wholly
black. Pronotum dark brown, with a paler median stripe, and the sides narrowly
yellow. Rest of thorax and the abdomen dark brown, the latter marked with
yellow near the tip. Legs brownish, the tibiae rather pale. Wings with wholly
brown venation ; pterostigma brown and very distinct; quite close to tip of wing.
Antennae rather short. Pronotum longer than broad, tapering in front. Abdo-
men quite large, especially at the tip. Wings broad, both pairs rounded at tips;
only very few of the veinlets on outer and posterior margins of wings forked, and
these only slightly. Length 14 mm.
The type is from Southern California. There is a specimen in
the National Museum from the same State. It is one of the most
remarkable and striking forms in the family as represented in this
country.

AliLOCHRYSA gen. no v.
Similar to Chrysopa, but the third cubital cell is nearly equally
divided, the divisory veinlet running into the end-veinlet of the cell
instead of into the upper margin. The antennae are quite long, their
bases close together. There are two full series of gradate veinlets in
each wing. Type A. virginica.
The two species known to me are separated as follows :
Pterostigma marked with brown ; large species; basal part of antenna? pale.

Pterostigma unmarked ; small species; basal part of antennae black, -parvula.
Alloolirywa virginica Fitch. — Green, unspotted ; but in life the abdo-
men is marked with reddish and yellow. Antenna? as long as wings. Pronotum
as long as broad, tapering in front. Legs very slender. Wings large and long,
fore pair rounded, hind pair acute at tips ; third cubital cell divided obliquely ;
both series of gradate veinlets are very full. Venation green, except the outer
gradate series which is brown, and sometimes the radial cross-veinlets are dark
at bases; pterostigma in both pairs with a brown spot at base, and in fore wings
there is a brown dot on the last veinlet connecting the cubital and median veins-
Length 19 mm.
The type came from Cartersville, Virginia. I have taken speci-
mens in the District of Columbia from oak trees in July, and have
co-types of N. phantasma MacGillivray from W. Chop, Mass., in
August; also from Florida. Have also seen a specimen from Staten
Island, N. Y., in August. This species appears to favor the oak
tree, and lives among the upper branches where its capture is most
difficult.
X llochrysa aiintilata MacGillivray.
I have not seen this species. In coloring of head and wings it
agrees exactly with Chri/sopa oculata, and I suspect it is a sport of
that species. It was described from Massachusetts.
Allodirysa parvula n. sp. — Face pale yellowish, vertex greenish, devoid
of markings; basal joint of antenna? pale yellowish, outside with a black line,
second joint and about a dozen following black, beyond pale; prothorax green,
margined on the sides with red-brown most broadly in front; rest of thorax
and the abdomen pale greenish, unmarked ; wings hyaline, veins green, most of
the transversals brown, pterostigma not distinct. Head rather broad, vertex with
a slight depression in the middle; antenna? about as long as wings; pronotum
short and broad, plainly narrowed near front; wings moderately long and acute
at tips, third cubital cell divided into two sub-equal parts by the divisory veinlet,
radial sector connected to the median by four cross-veins, beyond which there
are five branches of the sector. Length 11 mm.

One specimen from Runnymede, Florida. Bred from a white
cocoon enclosed in a mass of rubbish. It is the smallest of our spe-
cies of this genus, and differs from the others in that the median
vein runs straight to the hind margin and not into the second series
of gradate veinlets.
L.EUCOCHRYSA McLach.
General characters of Chrysopa, but antennae very much longer
than the wings. Pterostigma very distinct, brownish. The third
cubital cell is divided obliquely, but the divisory veinlet is nearly
straight, and starts close to the cubitus. The first connecting vein-
let from the radial sector back to the median extends basally before
the origin of radial sector (not so in Chrysopa). The genus, with
us, occurs only in the Southern States, and is more fully represented
in tropical countries. Type C. varia.

long, brownish, very distinct in both pairs. Antennas longer than the wings,
vertex somewhat elevated, hut flat on top; pronotum longer than broad, much
narrowed in front. Anterior wings broad, rounded at tips; hind wings rather
narrow, acute at tips; gradate series nearly parallel, seven to eight veinlets in

Specimens come from Lake Worth and Biscayne Bay, Florida,
and from Ocean Springs and Utica (August), Mississippi. It may
be the Chrysopa citri Ashmead, but his description may apply to
the next species, or to some species as yet unknown to me.

transverse red line, angulate in middle, reaching from eye to eye; pronotum
with a red mark on anterior sides. Wings with green venation, a few of the

pairs. Antennas much longer than the wings; vertex with two pits above; pro-
notum longer than broad, much narrowed in front. Wings rather narrow, the
fore pair nearly acute at tips, the hind pair plainly so. The gradate series con-
verge behind, the inner series of five veinlets. Length 15 mm.

The third cubital cell is unequally divided, the veinlet running
into the upper border of the cell. There are two series of gradate
veiulets in the wings, but sometimes one series is very short, espe-
cially in the hind wings. The antennae are rarely as long as the
wings. Type C. perla.

Very common throughout the Eastern United States and Canada.
Variable in size and breadth of wings. Some specimens with broad
wings and broadly rounded tips have more black on veinlets, and
may be a variety or even distinct species, but I cannot find any dis-
tinctive characters. These specimens appear to be most common in
early summer. The forms described by Fitch as illepida,fulvibucca
and mississippiends appear to me to be only forms of this variable
species. The life history has been described by Marlatt. His
figure of the larva shows its characteristic markings. The eggs are
laid in clusters. Adults are seen from early in July to September,
being most common in July. They are chiefly found in tall grass
and shrubbery, but sometimes on trees.

verse red line above, the second joint is blackish. The thorax and abdomen are
dark green, the pronotum with a few dark marks each side. The wingsare hya-

seem to be a northern form. It is distinguished from Ch. oculata
by the green gradate and other veinlets. Fitch's Ch. xanthocephala
and Ch. bipunctata belong to this species, and also, I believe, Ch.
bransmarina Hag., and Ch. latipennis Schn. All the specimens I
have seen were taken in July and August.
Chrysopa ypsilon Fitch.— This species is extremely similar to Chrysopa
chi, ami can best he described in comparison. The head is marked as is that spe-
cies, except that the median black mark forms a Y instead of an X ; the black
below antennal sockets is not connected above between antennae. The Y is some-
times connected to the snbmedian pair of black dots on the vertex. The thorax
is marked as in Ch. chi, as are also the wings, but the cross-veins are more heavily
marked with black than in that species. The wings have the same form. Length
] 1-15 mm.
I have specimens from Ithaca, Axton, Adiron. Mts. (June) and
Sea Cliff, X. Y. ; the latter were taken in May. I have also seen
specimens from New Jersey and Sherbrooke, Canada. It is very
close to Gh. chi, but the difference in head-markings appears to be
constant, Hagen records a specimen from Washington, D. C, but
I have not met with it here.
Chrysopa chi Fitch. — Head 'green ; a black spot under each eye, not con-
nected to eye, a similar black spot each side on clypeus, lower margin of anten-
na! sockets black, but not the outer margin, the black continued upward between
antenna' and divided in a Y, often connected to the submedian dots of vertex,
the entire mark forming an X, a black dot on vertex each side near eye ; all the
marks are shining black. Second joint of antennae black ; last joints of palpi
black ; pronotum green, with three black spots each side; rest of thorax, the ab-
domen, and legs green, each anterior lobe of the mesothorax has two black dots.
Wings hyaline, veius green, gradate veinlets and some cross-vein lets near base
black, many of the other cross- veinlets black at one or both ends, pterostigma
not very distinct; hind wings with the costal veinlets wholly black. Wings
lather broad, broadly rounded at tips. Length 14 mm.
Described by Fitch from New York.
I have specimens from Franconia, New Hampshire (Mrs. Slosson),
and Axton, Adiron. Mts., N. Y., June. Several of the specimens
have clinging to the wings one to three specimens of a little Cecido-
AMERICAN NEUEOPTERA. 149
myiid fly; the fly doubtless uses the Chrysopa as a means of trans-
portation.
C'lirysopa albicoi'iiis Fitch.— Head yellowish, a red spot on each side
of the clypeus, a blackish curved mark undereach eye, a broad blackish band
under antennal sockets extending upward between bases of an ten n x and then
bifid, sometimes connected to the two submedian dots on vertex ; upper margin
of antennal sockets narrowly margined with red-brown, and a red-brown dot
each side behind eye. Palpi banded with red-brown ; second joint of antenna-
blackish, basal joint sometimes with a red transverse mark above. Prothorax
green, each side with a few dark dots; rest of thorax, legs and abdomen green.
Wings hyaline, veins green or yellowish, costal cross-veins almost wholly black-
ish, many other cross- veins broadly black on bases or tips, gradate series black ;
in hind wings the costal cross-veins only are black. Length 11-12 mm.
Specimens are from Holly Springs, Miss. ; Marion, Ala. (July
2nd) ; Falls Church, Va. ; Burlington Co., N. J., and Sea Cliff" and
Ithaca, N. Y. All taken in July and August. Very close to Ch.
oculata. hut on the average smaller, and the cross- veins of wings
more marked with black.
I'lirysopa assimilis Banks. — Face yellowish ; a red-brown mark under
each eye, a broad transverse band under antennal sockets and extending upward
between tbem, above are two reddish dots, and two more on vertex, behind each
eye is another red dot. Palpi banded with red-brown. Second joint of antennse
black. Pronotum greenish, with some dark spots on each side; rest of thorax,
legs and abdomen greenish. Wings hyaline, veins green, gradate and cross-vein-
lets marked with black ; the veinlets connecting the median and cubital are
wholly black, as well as the divisory veinlet of the third cubital cell. Ptero-
stigma moderately distinct. In the hind wings the costal cross-vein lets are
wholly black. The fore-wings are broadly rounded at tip, the hind wings are
acute at tip; but four veinlets connecting the radial sector to median before the
gradate series. Length 14 mm.
Two specimens, the types, from Ashland, Oregon, Sept., 1897.
Similar in markings of head to Ch. oculata, hut differing in coloring
of veinlets of wings.
€/ln\vsopa uigricornis Burm. — Head pale green, a black spot each side
at base of clypeus, sometimes another black dot each side above this and below
the eye. Basal joints of antenna; pale green, beyond black Air about 15 joints
(1-5 of length) ; rest of body green ; wings with green veins, gradate series and
the costal cross-veinlets black, many other cross-veinlets black at one end ; ptero-
stigma quite distinct. Vertex of bead elevated in a triangular area, which is
depressed in the middle and the hind border an elevated ridge. Pronotum rather
short, plainly narrowed in front, transverse furrow very deep. Wings moder-
ately long, acute at tips. The inner series of gradate veinlets is often incomplete
toward tip, and in the hind wings is sometimes wanting. The divisory veinlet of
third cubital cell ends much beyond the cross-veiulet. Length 15-20 mm.

Specimens have been seen from Buffalo, Ithaca, Staten Island and
Sea Cliff, N. Y. ; Washington, D. C. ; Falls Church, Va. ; Colum-
bus, Ohio ; Onaga, Kans. ; Ft. Collins, Colo., and Sherbrooke, Can. ;
also from Mass. and R. I. They appear from June till September,
but apparently most common in June. Specimens vary in markings
of veins; sometimes many cross-veins are black only in middle. It
has been taken at electric lights.
Clirysopa lateralis Guerin. — Face pale yellowish, faint trace of red spot
each side near clypeus, vertex green, bordered in front just above antenna? with
reddish, basal joint of autennas marked with reddish on outer and upper side,
beyoud for about one-fourth length black. Pronotum green, with a red stripe on
each side, rest of thorax and abdomen green ; legs paler. Wings with green ven-
ation, the gradate series, costals for about one-half the distance, and most of rad-
ial cross- vein lets black ; many other cross-veinlets partly black ; pterostigma not
prominent. Antennae reaching to tip of wings; pronotum much narrowed in
front, trans verse groove very distinct. Wings long and narrow, acute at tips ;
the inner gradate series more or less incomplete. Length 15 mm.
It was described from Mexico. Hagen described Ch. pavida from
Mexico and South Carolina. I have seen specimens from South
Carolina and from Runnymede and Key West, Florida. The latter
was bred from a white cocoon covered with bits of bark and debris.
A specimen from Jalapa, Mexico, appears to be the same species,
but the red mark on the basal antenna] joint is very dark, and the
cross-veinlets are more black.
Chrysopa Columbiana n. sp. — Head pale yellowish, without markings,
thorax and abdomen pale green, second joint of antennas and beyond for about
one-fourth length black. Wings with green venation, gradate series and radial
cross-veinlets black, many other cross-veinlets black in part, very few black vein-
lets in hind wings ; pterostigma very distinct in both wings, pale brown in color.
Pronotum broad, very little narrowed in front, transverse groove not distinct.
Wings quite narrow, acute at tips. Length 13 mm.
One specimen from Washington, D. C. Related to Ch. nigricor-
nis, but the unmarked face and the black radial cross veinlets lead
me to consider it distinct.
Clirysopa lineaticornis Fitch.— Face almost white; vertex pale green ;
palpi white; basal joints of antennae whitish, with a prominent black stripe on
outer upper side, basal third of antennas beyond black. Prothorax pale green,
sometimes with a little reddish on outer edge; no yellowish stripe in middle;
rest of thorax and the abdomen dull green, the latter more yellowish near tip ;
legs whitish ; wings whitish green, green venation, gradate veinlets, costals, and
often the radial cross-veinlets black ; many other cross-veinlets more or less black ;
pterostigma quite distinct. Hind wings with costals browu, the pterostigma also

distinct. Antennae reach almost to tip of wings, the basal joints rather larger
than usual ; prothorax plainly narrowed in front, the transverse furrow is not
very distinct. Wings quite narrow, acute at tips. Length 13-15 mm.
It \v;is described from Central New York. I have seen specimens
from Franconia, New Hampshire; Agricultural College, Michigan,
July 12th; Bay Ridge, Maryland, July; Washington, D. C, July
16th, on pine; and Brookline, Mass. This may he the same as Ch.
ampla Walk., from Georgia, but I am not certain.
Ckrysopa coloradensis Banks.— Face pale green, a red-brown crescent
under each antennae, a red-brown stripe under each eye (not reaching to mouth),
and vertex with a reddish mark each side adjoining the eye ; palpi marked with
red; basal joint of antennae pale, second and beyond for about one-fourth the
length, black. Prothorax green, with a red stripe on each side; anterior lobes
of mesothorax reddish; legs pale; abdomen darker green. Wings with green
venation ; gradate series, the costals and the radials entirely, and the other cross-
veinlets partly black ; pterostigma rather distinct. Antennae not very long; pro-
notum broader than long, narrowed in front; wings moderately long, scarcely
acute at tip, except in the hind pair; divisory veinlet of third cubital cell end-
ing much beyond cross-vein. Length 14-17 mm.
I have seen specimens from Denver, Colo. ; Mesilla and Santa Fe,
New Mexico, July; Williams, Arizona, July ; Hood River, Oregon,
Sept.; Gazelle, Calif, Sept., and Pullman, Washington. It is a
very handsome species and not very closely related to any other form.
t'hrysopa sabulosa Banks.— Face yellowish, a triangular black spot
under each eye, a black spot under each antenna (but separated therefrom), and
a black dot above each antenna. Basal joint of antenna broadly marked with
black in front and on outer side, second joint black and the following ones also
to about one-fourth the length of antenna. Palpi marked with black. Thorax,
abdomen and legs green, unmarked. Wings with green venation, pterostigma
rather distinct. The antennae are rather short; the pronotum about twice as
broad as long; abdomen short ; wings rounded at tips, usually but one series (the
outer) of gradate veins, sometimes there are traces of the inner series. There
are not as many hairs on the veins as in most species. The divisory veinlet of
the third cubital cell ends beyond the cross-vein. The male genitalia is quite
elaborate, the lower part ends in three tufts of black bristles. Length 12-14 mm.
The type is from Colorado, and I have another specimen from
Southwestern Colorado, July 12th (Oslar). There is a male in the
National Museum collection from Las Cruces, N. Mex. (Cockerell).
It is a very peculiar species on account of the almost complete
absence of the inner series of gradate veinlets in both wing's.
Chrysopa explorata Hagen. — " Yellowish ; face with a large, quadrang-
ular spot, occiput with a Y-shaped streak and spot, red ; antennae yellowish ; fus-

cons at base; the first article yellow, with the apex above, red ; prothorax broad,
obliquely truncated in front; anterior margin black; wings hyaline, narrow,
pterostigma yellow, interiorly with a red spot; transverse veins of the anterior
wings almost all blackish-fuscous; gradate veins ~> and 5. Length to tip of
wings 13 mill." (Hagen.)
I have not seen this species, and copy Hagen's description above.
It was described from Mexico, but Hagen, in Wheeler's Report, 100
meridian, records a specimen from Arizona. I have not included it
in the table ; it belongs to the Ch. nigricornis group, and appears to
be very distinct from any of our other species.
Chrysopa rufilabris Barm. — Face yellowish or greenish, a red stripe
under each eye to mouth ; antennae pale yellow ; thorax and abdomen green, with
a pale yellow median stripe ; legs yellowish. Wings with green veins ; the gradate
veins black, and also the ends of some other cross-veins. In some specimens nearly
all of the cross-veins are more or less black. There is considerable variation in
the shape of the wings, some specimens (chiefly from the North) have broader
wings, and tips rounded : while southern specimens have narrow wings with
acute tips. The divisory veinlet of the third cubital cell usually ends just beyond
the cross-veinlet ; in specimens from the extreme South (Louisiana and Florida)
it ends directly in the cross-veinlet. This form may be the C. attenuata of Walker.
Specimens occur, however, with the divisory veinlet ending before the cross-
veinlet. Length 12 to 15 mm.
Specimens have been seen from Ithaca and Sea Cliff, New York ;
Washington, D. C. ; Falls Church, Va. ; New Brunswick, New Jer-
sey ; Medina, Ohio; Agricultural College, Mich.; Shreveport, La.;
Kissimmee and Biscayne Bay, Fla. Hagen records it from Georgia.
It is thus evidently spread throughout the entire eastern part of the
country. It occurs from June till October, on various trees, shrubs
and low plants. In life it is grass-green, with a pale yellow stripe
from vertex to apex of abdomen. It has a distinct fetid odor. It
Hies freely at twilight, and has been taken at lights. The life his-
tory was described by Fitch. The eggs are laid singly, not in groups.
The larvse are white, with dark stripes on the head. They carry
some debris on the body, which often conceals the insects. The
cocoon is snow-white.
Chrysopa interrupts Schneider.— Pale straw yellow throughout; a
reddish mark from each eye to the mouth. The gradate series wholly, and most
of the other cross-veinlets of fore wings brown, in hind wings but few cross-
veinlets other than the costals marked with brown ; pterostigma not very dis-
tinct. Antenna quite short; pronotum slender, longer than broad, narrowed in
front. Wings slender, acute at tips, divisory veinlet of third cubital ends beyond
the cross-veinlet. Length 12-13 mm.
AMERICAN NEUROPTERA. 153
Specimens have been before me from New Jersey ; Sea Cliff, New
York; and Washington, D. C, July; also from Penna. ; Selma,
Ala,, and Aurora, 111. Several were bred from snow-white cocoons.
It is very close to C. rufilabris, but in life lias no pale median, dorsal
stripe. It does not appear to be common anywhere.
I'hrj sopa quatlripuctata Burin.— Pale yellowish, a reddish stripe each
side efface from eye to mouth, vertex rather elevated, with two submedian pits,
antennae wholly pale, reaching to pterostigma of wings, prothorax plainly longer
than broad, suddenly narrowed at anterior third, beyond with parallel margins,
above with one or two transverse ridges and furrows, the anterior sloping side-
margins are reddish, and there are four or sis reddish spots above, often fading
in dried specimens, a red spot on each anterior lobe of the mesothorax, and often
some smaller ones between and behind these. Abdomen in life marked with
reddish and clear yellow. The wings are moderately broad, the fore pair barely
acute at tip, the hind pair plainly so at tip. Venation yellowish, the gradate
series black, the central cross-veins blackish at ends, some of the basal cross-veins
black, and often the bases of many others black; in hind wings the costals are
wholly black. The divisory veinlet of the third cubital cell ends much beyond
the cross-veins above. The gradate cells are subequal in length and but little
longer than those beyond. Length 14-17 mm.
It was described from Pennsylvania and Carolina; my specimen-
come from Sea Cliff, N. Y., August ; Ft. Lee, New Jersey; Austin.
Texas; Falls Church, Va., and Washington, D. C, in June on till
October.
This species I have always taken on or near oak trees. It has a
scarcely distinct fetid odor. The color is a rather pale green, paler
than C. rufilabris, and the red spots are very distinct, especially
those on the upper side of the first four segments of abdomen.
Chrysopa bimaculata McClendon. — Face pale yellow, unmarked; vertex
green ; antennae pale, the basal joint with a narrow red line above ; palpi marked
with black ; prothorax green, a bright red stripe each side, rest of thorax and the
abdomen green, unmarked ; legs paler Wings with green venation ; the gradate
series, the costals and the radials wholly black ; other cross-veinlets in part black :
hind wings with gradate series and radials in part only black; pterostigma quite
distinct. Antenme moderately long, vertex somewhat swollen : pronotum broader
than long, narrowed in front. Wings narrow, anterior pair barely pointed, hind
pair acute at tips; divisory veinlet of third cubital cell ends beyond the cross
vein. Length 11-13 mm.
Described from Laredo, Texas, August. Mr. McClendon sent me
specimens also from Laredo, and I have others from -\nstin, June,
and San Antonio, Texas; and from Biscayne Bay and Palm Beach
(Jan. 25), Florida.

Chrysopa emuiicta Fitch.— Pale yellowish green, abdomen darker green;
a reddish spot under each eye extending toward the mouth ; palpi marked with
black. Wings with green veins, the gradate series black, and the ends of many
other cross-veinlets also black ; pterostigma quite distinct. Wings large and
broad, the costal area broad, tips rounded in fore wings, in hind pair more acute ;
the divisory veinlet of the third cubital cell ends much beyond the cross-veinlet ;
there are eight to ten veinlets in the gradate series. Length 19 mm.
Fitch described this species from Central New York. I have
seen but one specimen which fits his description, it is from Franco-
nia, N. H. (Slosson). It is evidently an uncommon northern spe-
cies, and one of the largest in the genus.
C'hrjsopa erj throcephala Banks.— Pale yellowish green, abdomen
darker green ; a black spot each side near base of clypeus. Wings with green
veins; gradate veinlets black ; the costal and radial cross-veinlets are black in
the middle, green at ends; pterostigma not distinct. Antennae short; pronotum
narrowed in front, rather short. Wings quite long and broad, barely acute at
tips; gradate series of seven to nine veinlets; the divisory veinlet of third cubital
cell ends just beyond the cross-veinlet ; costal area not very broad. Length 18-
20 mm.
Specimens come from San Bernardino, Calif, July ; Mesilla, N.
Mex., July 18th ; and Pullman, Wash., July 3rd. It is easily dis-
tinguished by its large size, and by the costal and radial cross-vein-
lets being black in the middle, a peculiarity not found in any of our
other species.
Clirysopa medialis n. sp. — Face pale yellow, with a red stripe from each
eye to mouth, a red dot above and adjoining'each eye, sometimes a transverse red
mark across vertex; pronotum green, red on anterior margin, and a median red
stripe from end to end ; middle portions of meso- and metathorax marked with
ied, sides yellowish green ; abdomen pale green, with a median red stripe from
base to tip, widened on the posterior margin of each segment; legs pale green.
Wings with green venation, considerably marked with black ; the gradate series
and about all of the other cross-veinlets are black at the ends. Antennae rather
short; wings plainly acute at tips; the divisory veinlet of the third cubital cell
ends slightly beyond the cross-vein. Length 15 mm.
A few specimens were beaten from hickory foliage at High Island,
near the District of Columbia, in the latter part of September. In
life the red markings are very prominent, and the insect at once
reminds one of Ch. quadripunctata, but the arrangement of the
markings is very different.
Chrysopa cockerelli n. sp. — Face yellowish, a black stripe from each
eye to the mouth, connecting with each other. Antenna pale yellow ; pronotum
and thorax green, the latter with a slight reddish color on each anterior lobe;
abdomen and legs green ; wings with green veins, the cross-veinlets nearly all
black in part; the costal cross-veinlets wholly black. Antennas short, wings
moderately broad, scarcely acute at tips; divisory veinlet of third cubital cell
ends beyond cross-veinlet. Abdomen very short. Length 15 mm.
AMERICAN NEUROPTERA. 155
One specimen from East Las Vegas, New Mexico (Cockerell).
Separated from allied forms by the black (instead of red) stripe
under eyes, and the wholly black costal cross-veinlets.
Chrysopa arizonensi* n. sp. — Face pale yellowish ; a black dash below
each eye extending toward mouth, inward of this and below each antennae is a
red dot, above base of antennae is a transverse, angular, red line extending from
eye to eye, its angle projecting between bases of antennae; palpi mostly red-
brown; antennae pale. Pronotum pale, a narrow dark line on front of extreme
side margins; rest of thorax and the legs pale. Abdomen pale, when fresh pos-
sibly marked with dark at bases of segments. Wings hyaline ; veins green ; the
gradate veinlets, several basal veinlets, and parts of some of the other cross-vein-
lets are brown; in hind wings only a few veinlets brown. Pterostigma moder-
ately distinct. Antennae quite short; prothorax short, narrowed in front; wings
of moderate width, pointed at tips, divisory veinlet of third cubital cell ending
much beyond the first cross-veinlet from the radial sector. Length 12 mm.
One specimen from Yuma, Arizona (Morse, collector). Very
easily separated from all our other species of the genus by the angu-
lar red line on head ; a somewhat similar mark is in Leucochri/stt
americana.
Chrysopa plora lunula Fitch. — Pale greenish or yellowish, in life
showing a paler median, dorsal stripe, often fading out in dry specimens. A
straight brown mark under each eye, and sometimes a brown dot at each outer
anterior corner of the pronotum. Venation pale green or yellowish ; pterostigma
rather distinct. Pronotum short and broad, as broad as long, sides parallel, not
narrowed in front. Wings quite broad: anterior pair rounded at tip, hind wings
slightly acute ; divisory veinlet of third cubital usually ends on or just beyond
the cross-veinlet. Length 14-15 mm.
Specimens have been seen from Columbus, Ohio, March ; Agri-
cultural College, Mich, Febr. ; Boulder, Colo., Aug.; and Austin,
Texas, March ; also from Utica, Miss. ; Ames, Iowa ; and Luverne,
Minn. Fitch records it from Northern Illinois and New York.
The Michigan specimens had passed the winter in dead leaves and
in hedges. Shimer, under the name of Ch. illinoiensis, has given :i
long account of its life history.
CHrysopa liarrisii Fitch. — Pale green throughout in life, fading to yel-
low in dried specimens: a pale yellowish median, dorsal stripe. Cheeks suffused
with reddish ; sometimes a minute red dot on vertex near each eye. Venation
green, pterostigma quite distinct. Antennae moderately long; pronotum about
as broad as long, sides parallel, not narrowed in front. Wings slender, acute ;it
tips ; divisory veinlet of third cubital usually ends beyond the cross-veinlet.
Length 13-15 mm.
Specimens are before me from Washington, D. C, from pine trees
in July; Manchester, New Jersey, Sept. ; Staten Island, New York,

Oct.; Agricultural College, Mich., July; and Mt. Washington, N.
H. Fitch described it from New York in July and August. The
cocoon is yellowish, and is often seen on pine-needles; the larvae
feed on Chermes.
t'lir.ysopa calif bruica Coquillett. — Pale green or yellowish, with a pale
median dorsal stripe in life. Cheeks suffused with red, and often a red dot above
on vertex near each eye. Venation pale green or yellowish, pterostignia moder-
ately distinct. Pronotum about as hroad as long, sides parallel, not narrowed in
front. Wings rather broader than Ch. harrisi, and not quite as acute at tips.
The divisory veinlet of third cubital ends usually at the cross-veinlet. Length
13-15 mm.
Described from California, and I have seen specimens from many
places; Los Angeles, Tehama, Wanona, San Bernardino, Palo Alto,
San Mateo Co., Santa Clara Co. and Siskioii Co.; mostly in July
and August, but some in April. Also from Hood River, Oregon,
September; Pullman, Wash., July and August; and King's Canon,
Ormsby Co., Nevada, July. It is barely more than a variety of Ch.
harrisi, but I understand that Hagen considered it a distinct species.
It is the most abundant species on the Pacific Coast.
dirysopa externa Hagen.— Pale green or yellowish, not showing a dis-
tinct pale median stripe; cheeks reddish. Venation green, pterostignia not dis-
tinct. The pronotum is about as hroad as long, but the sides converge a little
forward. The wings are slender and acute at tips; the divisory veinlet ends be-
fore the middle of the cell and before the cross-veinlet. The venation is not as
dense as in the allied species. Length 11-14 .mm.
Specimens have been seen from Las Cruces, June, Santa Fe,
Aug., and Mesilla, New Mexico and also from Yuma, Arizona, and
Palm Springs, Cala. (Feb. 14th). The variation upon which the
specific name is based occurs also at times in the allies species, and
one of Hagen's specimens, that from D. C, must have been a Ch.
harrisii. Nevertheless I have retained the name for those specimens
which show the variation in an extreme degree.
ME LEO HI A Fitch.
. The genus has the venation about as in Chrysopa. The antennae
are more widely separate at base than in any of our other forms, and
in the male there is an inter-antennal protuberance or horn. The
basal joint of the antenna is more slender than in Chrysopa. The
species appear to inhabit mountains. Type is M. signoretti.
Our three species are separated by the following table :
AMERICAN XEUROPTERA. 157
1. Horn of male as long as width of vertex ; second and third joints of male
antenna? simple; no line on cheek in either sex; gradate veinlets
blackish signoretti.
Horn of male much smaller ; a black line on cheek 2.
2. Second and third joints of antenna? of male excavate on inner side; gradate
veinlets green slossonje.
Second and third joints simple ; gradate veinlets blackish ililiovala.
Meleonia signoretti Fitch. — Pale yellowish green. Face of male pro-
jecting in front in two reddish submedian tubercles; between antenna? arises a
prominent horn which is as long as width of vertex, and projects out horizon-
tally, its end bent vertically downward and provided with a stiff bifid brush of
pale reddish hair ; in the female this and the tubercle are lacking ; vertex elevated
transversely between the eyes. The antenna? are darkened beyond the base, but
not black, in length scarcely reaching to middle of wing. Prothorax a little
longer than broad, plainly narrowed in front, and with a transverse ridge beyond
the middle. Venation of wing green, with the gradate veins blackish, as also
the bases of the cross-veins from the radius, and one or two cross-veins in the
anal region, lower half of base of third cubital cell and connecting veinlet to the
radial sector and end of the divisory veinlet of third cubital cell black. Length
14 1(J mm.
Specimens come from Mt. \Yashington and Franconia, New
Hampshire, and from Sea Cliff, N. Y., July; Fitch's specimen was
from the Green Alts, of Vermont. The type was, according to
Hagen, purchased fur the Museum of Comparative Zoology, but there
is a specimen in the National Museum from the old Fitch collection.
Meleoma slossonse Banks. — Pale green or yellowish when dry, a red-
brown stripe from eye to mouth ; palpi marked with reddish, a dark spot on each
anterior side margin of pronotum. Venation green, many of the cross-veinlets
in part black ; pterostigma long and distinct. In the male there is a cavity in
middle of face below antenna?,, between bases of antenna? is a short, broad tuber-
cle, trifid at tip ; the vertex is transversely elevated from eye to eye. Antenna?
with basal joints slender and divergent, curved, concave within, second and third
joints short, fourth longer and swollen at base on inner side. In J there is no
tubercle, but a slight conical elevation ; the basal joints of antennae, are simple, as
also the fourth. Pronotum broader than long, sides nearly parallel, a little nar-
rowed at extreme front. Wings moderately long, anterior pair rounded at apex,
hind pair acute at tip. Length 18-19 mm.
Specimens have been taken by Mrs. A. T. Slosson from Mt.
Washington, Crawford Notch and Franconia, New Hampshire;
also seen from Brookline, Maine; and Quebec and Sherbrooke,
Canada. This species differs much from M. signoretti, in structure
of antennae and the tubercle. Mr. McLachlan in a note in Ent.
News, 1«S94, thinks that it is a sex of M. signoretti; however, there
is not the slightest doubt of their distinctness, and that the female
Me/eoma is without a horn.

Meleoma innovata Hagen. — Pale green ; a pale yellowish dorsal, median
stripe ; a red-brown stripe -from each eye to mouth; palpi marked with reddish.
In male the lower part of face is gibbous, a cavity above it marked with pink ;
between bases of antennse a small tubercle, bifid at tip and curved downward.
Basal joints of antennae divergent, and swollen near tip, especially below, beyond
simple. Female without these structural modifications, but the basal joints are
widely separate at base, and much more slender than in any Chrysopa. Wings
rather long and slender, anterior pair rounded at tip, hind pair acute at tip.
Venation green, some cross-veinlets marked in part with black ; pterostigma
quite distinct. Pronotum broader than long, not narrowed in front. Length
18-20 mm.
I have a pair ; male from Amecameca, Mexico, the female from
Santa Fe, New Mexico, July. At the time of my description of
M. mexieana, which was based on the former specimen, I had not
examined Hagen's description of Ch. innovata carefully. It is
strange that Hagen did not place this species in Meleoma, since he
states that it possesses the very character upon which this genus was

Characters in general those of Chrysopa, but there is but one
(the outer) series of gradate veinlets in hind wings; the branches
from the radial sector being curved and sinuate. In the forewings
the inner row of gradate veinlets are only three or four in number.
The wings are narrower than in most species of Chrysopa; the longi-
tudinal veins are usually marked with brown, and there is usually a
brown dot under the tip of each femur. Type Ch. punctinervis
McLach.
Three species can be referred to this genus, and they may be re-
cognized from the following table :
1. Longitudinal veins marked with brown 2.
Longitudinal veins not marked with brown, cross-veinlets almost wholly
brown hageni,
2. Transverse veinlets wholly brown, larger species fraterna .
Transverse veinlets interruptedly brown and pale, smaller species.
puiicliiiervis.
Eremoclirysa liageni n. sp. — Head pale greenish yellow, a black stripe
on each cheek reaching to mouth, second joint of antenna? blackish, first joint
above red-brown, beyond pale, rather darker towards tips. A black spot between
antenna? extending backward in the shape of a Y, its posterior tips enlarged.
Palpi red-brown, pale on base. Pronotum pale, a median narrow line, and some
spots each side dark ; rest of thorax and the legs pale Abdomen pale, evidently
with various dark marks when fresb, most of the fourth and the sixth and sev-
enth segments red-brown above. Wings hyaline, veins mostly pale, cross-vein-
lets mostly dark, except those of the costal area which are dark only at subcostal
AMERICAN NEUROPTERA. 159
ends. Vertex of head rather elevated at the dark spots; antennae quite short;
prothorax narrowed in front. Wings narrow, tips rounded, but three gradate
veinlets of inner series, four or five of outer series, but one series of gradate vein-
lets in hind wings. Length 10 mm.
San Antonio, Texas, and Austin, Texas, May 20th ; the latter
from Mr. McClendon. A very handsome and distinct species, not
very closely related to any other in our fauna.
Eremoclirysa puiictinervis McLach. — Head yellowish ; a blackish
mark under each eye reaching toward mouth, a spot between base of antenna' ;
palpi banded with red-brown ; basal joint of antenna? often with a red-brown
spot on inner upper side, a narrow line on outer side; second joint often with a
dark spot above, but not wholly black. Pronotum marked each side with red-
brown, as likewise meso- and metathorax ; abdomen somewhat marked with
brown ; legs pale, a brown dot under tip of each femur. Wings grayish hyaline,
veius and veinlets interruptedly pale and red-brown, sometimes some of the
cross-veinlets are wholly dark, gradate veinlets brown; hind wings similarly
marked. Wings narrow, rounded at tip, but three or four gradate veinlets in
each series, in hind wings but one (the outer) series of gradate veinlets, third
cubital cell about twice as long as broad. Length 9-11 nun.
I have seen specimens from Brazos Co., Victoria (March 29th),
and Austin, Texas; San Augustine, Las Vegas Hot Springs and
Mesilla, New Mexico; Williams and Winslow, Arizona; Los An-
geles and Palm Springs, Calif. ; and Colorado. Most specimens
were taken in Aug., Sept. and Oct., but those from Palm Springs
were captured in Feb. and March. In life it looks quite unlike
Chrysopa, and is of a grayish color. It appears to be the most
common species of the arid region of the southwest.
Eremochrysa fraterua Bauks. — Similar to E. punctinervis, but larger,
and more marked with brown. From between the antenna? two stripes run up
on the vertex, and the second joint of antenna? is wholly black ; the inner orbit
of each eye is margined with black. The thorax has a broad stripe on each side,
and a narrow median line ; there is a dark dot under the tip of each femur. The
cross-veinlets of the wings are all dark, the pterostigmatie ones broadly marked
with brown. Length 12 nun.
The type is from Colorado, but I have recently seen a specimen
taken by Mr. Baker at King's Canon, Ormsby Co., Nevada, June
6th, which agrees with the type in every particular.

SYNOPSIS OF .flEGACHILIDJ! 4i\D BOJIBINyE.
BY CHARLES ROBERTSON.
This belongs to a series of papers — Andreninse, Trans., 28, 187-
194; Halictinse, Can. Ent., 34, 243-250 — intended to bring together
in brief form the results of my studies of the local bees. My pur-
pose primarily is to facilitate the determination of the species. Con-
sequently, the more general groups sometimes give the common
characters of the local representatives instead of those of the same
groups as represented throughout the world. For example, the
Osmiini are described as "greenish, bluish or purplish," although
there are Osmiini which are black. The same applies to the
colors of Stelidini. I find that all of the local species of Ccelioxys
have the first joint of labial palpi shorter than the second. To
avoid repeating that fact in the table of the species, I give it under
the genus. It does not follow that all species of Ccelioxys agree in
that respect. So in other cases, in order to avoid repetition, I have
moved the statements of the common characters as far forward as
possible.
Also to facilitate identification I have made tables for each sex.
If you are trying to determine the female of Andronicus, it does not
help you very much to be told how the male differs from the male
of Alcidamea. The characters of the mouth parts are given under
the females and are not repeated for the males.
In this paper vein III, = the vein separating the stigma from
marginal cell; section 2 of vein III = the vein separating stigma
from first submarginal cell; section 3 of vein III = the vein sepa-
rating first submarginal cell from marginal ; III4 = third transverse
cubital nervure; vein IV2 = second recurrent nervure; vein \T, =
transverse medial nervure; section 2 of vein V = the principal sec-
tion of vein separating first and second discoidal cells; vein a =
basal nervure; vein m = section of subdiscoidal nervure forming
lower border of third discoidal cell ; segment = dorsal segment of
abdomen ; joint, unless otherwise indicated, refers to antennae ; supra-
orbital line = line drawn across vertex between summits of the e) eg
malar space = space between eye and base of mandible, its length
taken from the eye to a sinus a little before the middle of the base

of the mandible, its width taken on the line separating the base of
the mandible.
The basal tooth of the claw in females of Megachilini is not ho-
mologous with the inner tooth of the claw in females of Trachusa
and Anthidiinse, as is shown by males of Ceratias, which have the
same basal tooth and cleft claws.
Among the local Osmiini I do not find females with mandibles
distinctly quadridentate, except in Gnathosmia. The so-called
fourth tooth is a beveled angle between the two inner teeth and is
only seen when the mandibles are held in a certain position. None
of them have four external teeth like the female of Andronieus.
The difference between my arrangement of the Coelioxyini and
Stelidini and that of recent authors seems to imply that I have a
different opinion as to their relationship. I hold that the arrange-
ment proposed by these authors does not give a correct statement of
their own views. There is a possibility, or probability, that Stelis
was developed from Dianthidium. In that case Stelis and Dianthid-
i a in are more closely related than Anthidium and Dianthidium, and
the groups should show that relationship.
I had formed the opinion that Psithyrus citrinus 8m. was the male
of P. laboriosus F. before I happened to find a place where Walsh
has expressed the same view, in Proc. Ent. Soc, 3, 247, 1864.

middle ocellus, below this keel is continued nearly half way down the clypeus as
a raised line. Eyes nearly parallel, the space between on a line drawn across the
middle of the clypeus less than the space between on a line drawn across the front
anterior to the middle ocellus. Clypeus convex, with a narrow polished margin.
Labrum concave, the punctures coarse close together but not well defined;
sparsely covered with bristles, more copiously with short soft hairs. Mandibles
curved, the tip of one extending almost as far as its fellow. Scape about as long
as the first three joints of flagellum combined, hardly thicker than the flagellum.
Thorax. — Sculpture of dorsum largely hidden by the abundant pale dull yel-
lowish pubescence, the exposed portions closely indistinctly punctured, granular.
Scutellum with a stout spine on each side directed backward, the spine as long as
the pubescence, about one mm. Metathorax on the posterior aspect sparsely
covered with black hairs, indistinctly punctured and dullish except for a trian-
gular area which is depressed along the middle, rugulose near its base in greater
part smooth and shining ; the apex of this triangular area is about two-thirds the
distance from the superior margin of the posterior aspect of the metathorax, from
this apex to the insertion of the abdomen is a narrow sulcus. Sides of the thorax
thickly clothed with black pubescence, the sculpture like that outside of the tri-
angle on the metathorax. Legs in greater part covered with short black hairs;
tarsal claws cleft the parallel tooth extending nearly to the middle of the long
claws. Wings hyaline darkened with brown but not strongly, nervures black or
almost; first recurrent nervure received by the second submarginal cell a little
beyond the middle, the second recurrent received by the third submarginal cell
at the middle or nearly; transverse median nervure in posterior wings origina-
ting some distance before the origin of the cubitus.
Abdomen with minute indistinct punctures separated by small spaces; some
bristle like hairs at base, sides and on the margins of slight depressions on the
segments, otherwise covered with a fine appressed dark (black) pubescence which
almost hides the character of the sculpture and has brown, purple and bluish re-
flections in certain lights, the rich deep royal blue predominating. Pygidial area
with slightly raised margins, finely granular, dullish
Jet Black excepting antennae, mandibles and legs which have a more or less
brownish tendency.

NOTES ON S(Mli; GENERA OE IS I IS.
BY T. D. A. COCKERELL.
A few years ago Mr. J. Vachal sent me a lot of critical comments
on Mr. Ashmead's "Classification of the Bees" (Trans. Am. Ent.
Si >c, xxvi). At the time, I suggested that he should publish them ;
but I believe he has not done so, and as many of them are import-
ant, I present them here. I add various remarks of my own, but
in every instance Mr. Vachal's observations are carefully credited
to him. The paper is intended to be supplementary to that of Mr.
Ashmead, contributing facts which will have to be considered when
a revised classification is prepared.
NOMIOIDES Schenck.
According to Mr. Vachal there is no rima or furrow on the fifth
dorsal segment of the female, as in other Halictinse. However, in
a female of A. variegatus from Triest, June 8, 1897 (Ducke, com.
Friese), it is distinctly present, though lacking the fringe of hairs
seen in Halictus. In A. pulchellus I find the maxillary palpi twice
the length of the galea, six jointed, the joints about equal, except
the first, which is shorter. The labial palpi have four joints of
equal length, or approximately so. The mouth-parts are essentially
as in Halictus. Mr. Vachal says Nomioides is not Lucasius, a genus
" founded on two aberrant male Halictus, of which the females are
true Halictus." I have Lucasius, and it is not at all like Norn wide*.
DIOONIA Gribodo.
This cannot go in Sphecodinpe. Mr. Vachal writes : "Didonia,
after the description of Gribodo, is not destitute of pollen-collecting
apparatus: 'Pedibus posticis autem ut in Amdrenis, flocculo pollini-
gero trochanterorum magno ; ' Gribodo put it in Andrenidse, Latr.
= Panurgidre, Ashm."
CAUPOLHASTA Spinola.
Mr. Vachal states that the second and third cubital cells are not
equal, the second is much shorter, the first recurrent nervure almost
or wholly interstitial with the first transverse cubital nervure. As
a matter of fact, Caupolicana is quite identical with Megacilissa.
TRANS. AM. ENT. SOC, XXIX. MAY. 1903.
184 T. D. A. COCKERELL.
More or less green or purple forms, confused with Megacilissa, be-
long to Ptiloglossa Smith, which in Ashmead's tables is placed with
Andreninse.
MYDROSOMA.Smith.
Ashmead has it Madrosoma; Mr. Vachal pointed out the error.
This has an obtuse emarginate tongue, and seems to be a genuine
Colletid, differing from Colletes by its metallic tints. In Caupoli
cana (C. yarrowi Cresson) the tongue is short, but deeply divided
into two long narrow segments, which are thickly covered with long
bristles. The labial palpi are short and thick, the first joint very
stout and as long as the next two together, the second and third
short and cordate, the fourth swollen-cylindrical, and decidedly
longer thau the second or third, which are equal to one another.
The short six-jointed maxillary palpi have the first joint much the
longest, as long as the next three together, 2 to 5 suboval and about
equal, 6 long-cylindrical, nearly as long as 4 and 5 together. The
galea, though short, is longer than the palpus, and bears long bris-
tles at its end. The teeth of the maxillary comb are extremely
long. The form of the maxillary comb, with the lower teeth longer
and curved, is quite as in Colletes. While Caupolicana is not so
like Colletes as Mydrosoma must be, I think there is no question that
Ashmead is right in including it with the Colletidse. The form of
the palpi is quite suggestive of Scolia.
PROTOXiEA Ckll. and Porter.
This is not related closely to the Colletidse. Compared with a
Scolia (? /nematodes') from Las Vegas, N. M., the mouth parts show
the greatest possible similarity, so that I must regard Protoxcea as
derived from the Scoliidse, or rather both from a common ancestor
having a similar mouth. The long first joint of the labial palpi of
Protoxcea appears to be produced by the chitinisation of the area
between the first joint (very short) in Scolia and the mentum, that
is, of the palpiger. Thus, the labial palpus represents palpiger and
the first joint of palpus fused. Scolia has a marginal comb on the
galea, which is lacking in Protoxcea, which has not even the ordin-
ary maxillary comb.
The differences between Protoxcea and the Scoliidse, aside from
the mouth-parts, at first sight seem very great, but there are resem-
blances which should not be overlooked. In particular I find a cer-
HYM E NOPTE K A . 1 85
tain similarity in the wings, which, though not extending to details.
appears to be significant. The coarse punctures on a shining ground,
and to some extent the form of the thorax of Scotia are indicated in
the bee genus Temnosoma, though not in Protoxcea. The eyes of
Protoxcea are not emarginate, but they are so in many Halictine
bees, while the Myzinid wasps have them so in the male, but not in
the female.*
The mouth of Temnosoma could be derived from that of the Sco-
lia-Protoxcea type by the shortening of the tongue, paraglossse and
first joint of labial palpus; the tongue, as in Hatictvs and Cilissa,
preserves the peculiar tapering form of Prctoxcea. The galea in
Protoxcea shows no sign of the apical division seen in Scotia, but in
Nomia and Hatictus it is plainly indicated, and Nomia (which Mr.
Vachal considers nearer to Hatictus than to Andrena) has also the
tapering tongue, broad basally and filiform apieally. A very inter-
esting genus is Meroglossa Smith, which assuredly does not belong
to the Prosopidse. The arrangement of its tongue and paraglossse
is quite suggestive of Protoxcea, but the maxillary palpus is very
much longer than in that genus. The venation is quite different.
The present conclusion is, that the whole series of Halictine bees,
at any rate, came from an ancestor not far removed from the Scolii-
dve. Protoxcea is of course not an Halictine, but it is from the same
general stock, and apparently nearer to the Scoliids than is Hatictus.
We seem to have divergent rather than successive types, but further
study will no doubt make the true relationships much clearer. Ir
may be added that Myzine and the Tiphiids have the tongue short
and rounded, not in the least as in Scotia. The mouth of Scut in i.-
in most respects far more like that of Protoxcea than it is like that
of the Myzinids or Tiphiids, though the latter have the divided
galea f of Scotia.
I do not think the Colletidse have any bee-ancestry in common
with the Halictines. So far as the mouth-parts go, Colletes shows
the closest possible resemblance to Tachytes, the resemblance extend
* Allied to the Seoliidse are the Thynnidae and Corynura Spinola, as Mr. Vachal
remarks, was based on a 9 Thynnid and a % Halietid ; a fact indicative of close
resemblance.
f Kellogg (Am. Nat., Sept., 1902) calls the part here designated the galea, tin
maxillary lobe, and says it consists of the galea and lacina fused. So I suppose
that the apical part in the Scoliids, etc., is the true galea, and the rest the lacina
TRANS. AM. ENT. SOC, XXIX. (24) MAY, 190.'i.
186 T. D. A. COCKERELL.
ing to the peculiar form of the tongue, and the comb along the mid-
dle of the maxillary blade, The prothorax in Tachytes is of course
much more bee like than that of Scolia, and one has to remark that
the eyes in Tachytes are extraordinarily similar to those of Protoxaza,
converging just the same above. The pygidial plate of Tachytes is
also suggestive of the bees. In Gorytes the tongue is very broad
and truncate, but not emarginate, and the paraglossae are broad ;
the comb of the galea is well developed. Gorytes does not stand
so near to the bees as Tachytes.
The tongue, paraglossse and labial palpi of the Australian genus
Hyleoides Smith, as figured by Smith, are almost precisely those of
Odynerus, even to the spots on the tongue and paraglossse. I do
not know how to explain this; one cannot well believe a bee genus
to have been derived from the Eumenidse, although the colors of
Hyleoides do rather resemble those of that group. Whether Pro-
soph could he derived from such a type as Hyleoides, I do not
know, but it seems to me to closely resemble Colletes in its mouth,
and if Colletes is derived from a wasp with a Tachytes like mouth,
there is no room in the series for such a type as Hyleoides. The
maxillary blade of Prosopis is quite like that of Colletes, except that,
as in the higher bees, the comb (of about six teeth) is wholly below
the palpi ; the maxillary palpi are much longer than in Gollrt, ■>■.
The labial palpi and tongue in the two genera are no, essentially
different.
It is to be observed that the bifid tongue is doubtless the older
type. The Sphecoidea, Eumenidse and Vespidse are in this respect
more primitive than the Scoliidse and the majority of the bees. A
Braconid examined has a long divided tongue, which would do very
well for a Eumenid, but it has not the Eumenid paraglossse.
PASIPHAE Spinola.
Mr. Vachal remarks that this has a distinct tibial pollen -brush,
and cannot go with the Prosopidse. It appears to be a Colletid with
only two submarginal cells.
It I AIM O I. IV \ Dufour.
This of course is an Andrena with two submarginal cells. Mr.
Vachal states that the sixth ventral segment of the % has lateral
projecting points as in Parandrena. I possess the 9 only; the
abdomen is very strongly and excessively closely punctured; the
metathorax suggests Trachandrena.
HYMENOPTERA. 187
SCRAPTER Lepeletier.
Dalla Torre gives this as a synonym of Macropis. Mr. Vachal
" Scrapter St. F. and Serv. 1825, is not Scrapter Lep., 1841, and
Ashm. ; the latter = Panurginus Nyl." He also adds that Scrap-
teroides Gribodo is Panurginus. Scrapter andrenoides Smith is no
doubt an Andrenid with two submarginal cells.
DASYPODA Latreille.
Mr. Vachal remarks that the tip of the marginal cell is acute and
contiguous with the margin of the wing. In D. argentata var. brae-
cata (Rads.) from Deliblat (Friese) I find the tip of the marginal
cell practically as in Macropis labiata. In D. hirtipes the same. It
diverges from the costa to a minute degree, and is briefly appendi-
culate.
PS.OYTHIA Gerstaecker.
Mr. Vachal states that this is nearer to Camptopoeum and Calliop-
sis than to Andrena. That is to say, it is a Panurgine with three
submarginal cells. I think Protandrena is also related to the Pan-
urgids, but it is really a connecting link between these and the An-
drenids, as shown by the short tongue.
ASfCYLA Lepeletier.
Mr. Vachal remarks that this is not an Andrenid ; he adds :
" Dalla To..e was wrong in putting it as a synonym of Andrena ;
but he corrected his mistake at p. 614 ; at p. 250 he has put Plisto-
trichia Mor. (nee Pristotrichia Radoszk , which is the same genus,
between Eueera and Meliturga, where is its true place." Smith
placed the genus between Andrena and Nomia, which no doubt
resulted in confusion.
With regard to Eueera, I believe it is the European representative
of our Synhalonia. The resemblance in the ornamentation of the
abdomen between the females of Eueera longicornis and Synhalonia
frater is quite remarkable. E. Saunders says the maxillary palpi
of Eueera are 5-jointed ; in E. (macrocera) ruficollis Br. from Alge-
ria ( Vachal), I find them 6-jointed, counting the thick basal joint,
which is easily overlooked. In Meliturga clavicornis they are also
6-jointed. Meliturga is a peculiar genus, the $ with large eyes
converging above, quite as in Protoxwa. The labial palpi have the
first two joints flattened (the first very much the longest), but still
not excessively differentiated from the last two, which still remain
TKANS. AM. ENT. SOC, XXIX. MAY. 1903.
188 T. D. A. COCKERELL.
nearly in a straight line with them. The tongue is quite as in the
long-tongued bees, but only moderately long. The apex of the <?
abdomen is bispinose, recalling Oxim. The $ antennae are strongly
clavate, but those of the 9 would do very well for an Andrena. The
marginal cell is obliquely truncate; the first recurrent nervure
meets the second transverso-cubital as in Protoxcea. The female
abdomen looks like that of an Andrena. All of this beautifully
connects the Anthophorid bees with the Andrenoid and other primi-
tive types, which we concluded to be derived from ancestors allied
to the Scoliidse.
STEGANOMUS Ritsema and CTENOI'LECTRA Smith.
These do not belong to the Megachilidse according to their
authors, Mr. Vachal remarks. Smith thought Ctenoplectra near to
Macropis, remarking : "The posterior legs have a dense clothing or
pollen brush as in that genus." Steganomus was separated by Rit-
sema on a % , "he said that his genus was closely allied to Nomia,
that is, a Nomia with two cubital cells" (Vachal). Smith put Oya-
thocera (== Steganomus) in the Andrenidae near Nomia, and said of
the 9 that the posterior legs have the tibiae and basal joint of the
tarsi furnished with a dense scopa. Mr. Vachal thinks Mr. Ash-
mead was misled by what appears to be a typographical error in
the table in Bingham's work on the Hymenoptera of India, whereby
these genera appear to go with those having an abdominal scopa.
Mr. Vachal adds that the species of Ctenoplectra from Africa (C
antinorii Gribodo) which he has before him has the three last seg-
ments of the abdomen fringed.
EUASPIS Gerstaecker.
Mr. Vachal has the 9 of the two species of this genus, and says
both are without scopa, ventral or tibial, so the genus should go in
the Stelidinae.
ALLOD4PE Lepeletier.
Mr. Vachal states that this has a tibial scopa in the 9 ; he thinks
it belongs next to Ceratina.
MACROPIS Panzer
This is not a Panurgid, according to Mr. Vachal ; he says it is an
isolated genus of uncertain affinities. It appears to me to be a
modified Andrenid, but it wholly lacks the lateral facial depressions
HYMENOPTERA. 189
of Andrena. The mouth-parts do not appear to be essentially differ-
ent from those of the Andrenids, and many characters of the abdo-
men, wings, etc., are strongly suggestive of Andrena. These re-
marks are based on the European M. labiata; the American M.
ciliata has an abdomen strongly recalling Exomalopsis solani. The
American M. steironematis Rob., with its densely punctured abdo-
men, looks very different from labiata or ciliata, but it has the
Macropis mouth.
AMTHOCOPA Lepeletier and €HAL,ICODOI»I A Lepeletier.
Mr. Vachal observes that Lepeletier cared more for the habits
than the form of bees, for founding generic groups; thus Anthocopa
(wrongly credited by Ashmead to Latreille) was based on Osmia
papaveris Latr., which is a petal -cutting bee, thus resembling the
leaf-cutting megachile; while Chalicodoma, a Megachiline, makes
mud-mortar cells.
IIOKKMIMA Dalla Torre.
As Mr. Vachal says, this was merely a new name for Epeicharis
Rad., and so cannot differ from it. Ashmead has a separate genus
called Florentina, D. T., apparently intending Fiorentinia. The
characters given by Ashmead for " Florentina " appear to belong to
Fiorentinia; those given by him for Epeicharis Rad. do not belong
to that genns, the maxillary palpi being said to be two jointed. Is
there not some confusion with Epicharis Klug. ?
EPK'LOPUS Spinola.
This genus ("Epicolpus" in Ashmead) is said by Mr. Vachal not
to be an Anthophorid, but to be hardly separable from Melecta. Its
blue color is peculiar. In this connection one may remark on the
beautiful and extraordinary patches of bright blue appressed pubes-
cence on the head, thorax, legs and especially abdomen in Crocisa
splendidula Lep. from Africa, a specimen of which I owe to the
kindness of Mr. Vachal. Something of the same sort is seen in
Ash mead's Xylocopid genus Cyanosderes.

NEW NOCTUIDS FOR 1903. No. 4, WITH NOTES ON
CERTAIN DESCRIBED SPECIES.
BY JOHN B. SMITH, SC.D.
The first paper of this series is in the Can. Ent., xxxv, pp. 9-15,
and 6 species are there described ; the second is in the Journal of
the New York Ent. Soc, xi, p. 1-23, and 21 species are there de-
scribed. In the present paper 34 new names are proposed, and
there are critical notes on the species of Raphia, Fishia and Aeon-
tin. It was intended to add to this a revision of the species belong-
ing to the Eucalypterid series; but a fire in my laboratory destroyed
some of my notes and disarranged the material to such an extent
that it will be impossible to do systematic work for some time to
come.
Under the circumstances it was deemed best to present the spe-
cies already in manuscript in this paper.
Notes on the Species of RAPHIA Hbn.
For many years two species of Raphia oidy were in our codec
tions — abrupta Grt and /rater Grt. Both of these are eastern spe-
cies, and, while they are undoubtedly distinct, it is not always easy
to separate them. Frater is common and variable; abrupta is rare
and its range of variation not yet understood. Quite usually a
somewhat obscurely marked frater does duty for abrupta, of which
I have only one pair in my collection at present. The 9 is from
Brazos County, Texas, and the female from Colorado ; which docs
not accord at first blush with the term "eastern species;" neverthe-
less, the faunal region is really the same.
Abrupta may be most readily distinguished by the dusky second
aries of both sexes, and in this it differs from all the other species.
In addition, the ground color is a dull obscure gray as compared
with the dark rather clear gray of frater. In the %, abrupta is
narrower winged, the outer portion of the wing is paler beyond the
t. a. line and above the claviform, the claviform itself is well marked
and extends to the t. p. line. In the 9 these characters are ob-
scure and, except for the dusky secondaries, it would be difficult to
to distinguish from frater.
TRANS. AM. KNT. SOC. XXIX. (24 JUNK. 1903
192 JOHN B. SMITH.
Frater has the primaries uniformly gray, and all the maculation
is rather evenly relieved, though by no means prominent or con-
trasting. The specimens before me range from Ontario, Canada, to
Winnipeg, Manitoba; south to Denver, Colorado, and east to New
Jersey. While there is considerable difference in appearance, there
is no variation in the essential characters.
In 1886 Mr. Putman Cramer described B. coloradensis as a
variety of frater, and so it remained until Dr. Dyar in his catalogue
of 1902 correctly listed it as a good species. The type of macula-
tion is like /rater in all essentials; but instead of an even dark gray
the primaries are mottled. The ground color is much paler, rather
whitish in fact, with a slight tendency to a yellowish suffusion,
while the maculation is much more contrasting. In general the
base and lower half of the median space are heavily black powdered,
while the remainder of the wing is whitish ; a blackish patch mark-
ing the inception of the median shade on the costa and usually some
sort of dusky spot indicating the reniform. There is a tendency to
lose the orbicular, while the claviform is well marked. I have one
female from Phoenix, Arizona, and the balance of my series is from
Colorado, partly of Mr. Bruce's collecting, partly from Prof. Gil-
lette, and partly of the Hulst material. The Arizona example is
dated January 11th, the others are not dated, nor have any of them
specific localities.
Also in 1886, and only a month or two later than the description
of coloradensis, Mr. Henry Edwards published Raphia pallula from
California as a good species, apparently without a knowledge of Mr.
Cramer's species. In my list of 1891 I made this a synonym of
coloradensis, and so it remains in Dr. Dyar's catalogue. I have re-
cently re-examined the types, which are now in the American Mus-
eum of Natural History. There are two specimens, both females,
and while fully expanded, they suggest cripples; possibly because
the primaries are so very broad, and the secondaries are proportion-
ally smaller than in the other species. The yellow suffusion is here
in the disc of the primaries involving the upper part of the median
space in which the black filled reniform stands out prominently,
while the orbicular is altogether lost. The terminal space is dark,
and in this particular it differs from all the coloradensis now at hand.
The examples are : one from Soda Springs, the other from Siskiyou
County, California. I have nothing that agrees with these speci-
AMERICAN LEPIDOFTKRA. 193
mens now before me, and I have had none from other sources. The
resemblance to coloradensis is marked, and had I received such speci-
mens from Colorado, I would have had no hesitation in placing them
as aberrant or discolored examples of that species. Under the cir-
cumstances, since there is really nothing to show that the distinctive
characters are not permanent, it will be better to restore Mr. Ed-
wards' name to specific standing.
For some time I have had in my collection three examples of
another species from Los Angeles County, California, differing from
all the others in the very even and very powdery light gray prima-
ries on which the markings are only a little relieved. In the even
color it differs from coloradensis, and in the very light powdery gray
it differs from frater. From all the species it differs in the practical
absence of the claviform which is barely indicated in only one ex-
ample. There are other differences in detail which convince me
that a good species is under observation, and to this I have applied
the name Cinderella.
Rapllia Cinderella n. sp. — Very pale ashen gray, powdery; tending to-
ward a yellowish suffusion, the markings blackish, not contrasting. Head with
a dark line across the front and another on the vertex. Collar with a dark line
across the middle and another at tip. Patagia margined with blackish, and the
posterior thoracic vestiture dusky. The disc of the patagia yellowish. Prima-
ries with all the maculation present, darker than the ground, not contrasting and
sometimes almost lost in the general gray powdering. The tendency to yellow
tinting is mainly in the basal and s. t. space, while the blackish powderings tend
to mass along the inner margin. Basal line obscure, usually marked as a dusky
spot on the median vein at base. T. a. line geminate, the component parts widely
separated, inwardly oblique to the submedian vein, then with a long outcurve to
the inner margin near its middle. T. p. line geminate, even, slender, the outer
part obscure; rarely evenly and not deeply bi-sinuate, the course as whole par-
allel to the outer margin. There is a diffuse, irregular, broken median shade,
best marked by a dusky spot on the costa, obviously but less distinctly below the
submedian, S. t. line whitish, relieved by an irregular preceding dark shade in
the s. t. space. A series of blackish terminal lunules. The fringes are dusky,
cut with whitish opposite the veins. Orbicular round, moderate in size, consist-
ing of a dusky annulus which may or may not have a central dot in the inclosed
area. Eeniform varying in size and somewhat in shape, with a dark outline and
a dark central lunule which may extend to fill the entire spot. Secondaries
white, with a series of blackish terminal lunules, and a blackish spot at the anal
angle. Beneath white, powdery ; primaries with a vague tendency to reproduce
the most obvious markings of the upper side, especially the reniform ; seconda-
ries with a small discal lunule. Expands 1.36-1.48 inches = 34 37 mm.

Hab. — Los Angeles Count)', California, in May.
Three male examples are now before me, two taken by myself
and one by Mr. Coquillett. The latter' is from National Museum
material in which the species is represented by additional specimens.
The characters differentiating the species have been already com-
mented upon.
Hadena tonsa Grt., Can. Ent„ xii, 214, 1880.
This species I saw in the British Museum in 1891, and it was at
that time unknown to me. Examples came to hand in 1898, but 1
failed to recognize them and redescribed the species as Hadenella
subjuncta in the Can. Ent., xxx, 323. A re examination of the
type of tonsa in 1890 suggested the above synonymy which was con-
firmed by a comparison of my material later. Mr. Grote's example
came from Nevada ; the material at present in my collection is from
Washington and Calgary ; I believe I have seen examples also from
Colorado, but have seen no eastern examples.
In Dr. Dyar's Catalogue, Bull. U. S. Nat. Mus., No. 52,. p. 108,
minuscula Morr. is placed in Hadenella, with subjuncta as a syno-
nym. Orthosia minuscula Morr., referred to Parastichitis by Mr.
Grote and later to Hadena by myself, has absolutely nothing in
common with tonsa (subjuncta') ; not even wing-form. It does not
belong to Hadenella, is a medium sized, broad winged, red brown
species, with very simple maculation, and belongs to the fauna of
the North Atlantic States. The type is in the Tepper collection,
and I have recently seen the species in the Mus. Comp. Zool., from
the Thaxter collection.
Hadena exhausta n. sp. — Ground color a pale creamy gray, varying a
little toward a brownish shading. Head with a black or brown line across the
front, and another on the vertex. Collar with a black or brown transverse me-
dian line. Thoracic vestiture brown tipped. Primaries with the broad basal
space gray; the median space which narrows greatly toward the inner margin is
brownish or blackish, varying in shade but not striking in contrast; the s. t.
space is gray, interrupted in the submedian interspace by a black shade line
which continues from a black shade connecting the median lines to the outer
margin above the hind angle. Terminal space variably dark shaded. Basal line
geminate, obvious only across the costal area. T. a. line well removed fron base,
geminate; inner line marked on costa and traceable part way across the wing by
brown scales; outer line slender, black ; included space whitish, or at least paler
gray ; as a whole the line is obliquely outcurved or almost evenly oblique to the
internal vein, reaching the inner margin only a little within the middle. T. p.
line geminate, the component lines widely separated, included space whitish or

lighter gray ; inner line hlack or blackish tending to become discontinuous ; outer
line punctiform.niore or less incomplete; as a whole the line is broadly outcurved
over the cell, then inwardly oblique to the internal vein where it approaches
nearest to the t. a. line. S. t. line somewhat diffuse, smoky, only a little irregu-
lar, more or less emphasized by venular dots or shades which sometimes extend
toward the outer margin, darkening the terminal shade. A black lunate termi-
nal line. Fringes with a smoky, lunate interline, the margin a little scalloped.
Orbicular absorbed in the basal space, the outline of the outer margin forming a
little irregularity in the t. a. line. Reniform large, broad, kidney shaped, more
or less completely outlined by black scales, within which is a paler annulus ; the
spot as a whole of the ground color but more or less marked with smoky brown.
Claviform short, broad, outlined by black scales, suffused by a blackish or brown
shade which crosses the median space above a narrow hlack connecting line.
The internal vein is white through the median space and cuts hoth median lines,
which diverge below it. forming at this point the narrowest portion of the space.
Secondaries smoky, glossy, with a vague outer line. Beneath powdery gray;
primaries tending to smoky ; secondaries with an exterior smoky line and discal
dot. Expands .88 inch = 22 mm.
Hab.—New Windsor, N. Y., July 9, 29 (Miss. Emily L. Mor-
ton) ; Schenectady, N. Y. (Lintner).
This species occurs throughout the North Atlantic States, but is
not common. It is the species that I have called hausta in my own
and other collections for years.
My original specimen came to me years ago in such a way that I
believed the determination has been made by Mr. Grote, and a
hasty reading of the original description which compared the spe
cies to modica did not raise any doubts as to the correctness of the
name. More recently Mr. Merrick sent me from New Brighton,
Pa., -pecimens that seemed closely allied and familiar in appear-
ance; but I could not then recognize the form and sent it back
unnamed. In the U. S. Nat. Mus., I again saw the two forms asso-
ciated in such a way as to bring out the contrasts between them and
to make it certain that two species were at hand.
Comparing Mr. Grote's original description carefully, developed
the fact that Mr. Merrick's examples are the true hausta, while the
hausta of my collection seems to be an unnamed form. It can be
readily recognized by the broad creamy gray basal space, the
V shaped darker median space, and the black line extending across
the s. t. space in the submedian interspace. In hausta the base of
the wing is brown and everything beyond the middle is creamy
gray. Seen apart, the two species give a very similar impression ;
seen in comparison their difference is obvious.

Leucania texana Morr., Proc. Bost. Soc. Nat. Hist., xvii, 211, 1874.
Mr. Morrison refers under this name to what he considered a
variety of L. phragmatidicola from Texas, and gives dates for the
specimens. In my recent revision of the species of Leucania I
quoted the essestial parts of Mr. Morrison's description ; but failed
to identify it with any -form of the species to which it was referred
as a variety. It seemed scarcely credible that Mr. Grote's sugges
tion as to the species could be correct, especially as he gave the
name ligata to the form he thought Mr. Morrison might have had
before him. In looking over the material in the Cambridge collec-
tion recently, I found a small series of specimens labelled phragmati-
dicola var. in Mr. Morrison's handwriting, and three of these exam-
ples agree in locality and dates with the facts stated in the descrip-
tion of texana. The specimens came from Belfrage, are from the
Peabody collection, and without any doubt the specimens Mr. Mor-
rison had before him when he wrote; in other words, they are the
types of Leucania texana Morr. They prove that Mr. Grote was
correct in his surmise, and that texana Morr. is really the same as
ligata Grt. The latter name must sink as a synonym and texana
must take specific rank in its place.
Leucania flabilis Grt., Can. Ent., xiii, 15, 1881,
This species was described from Long Island, and up to this year
I had seen only the typical examples from the Tepper collection.
Recently, while looking over the collection of Mr. Philip Laurent,
at Mt. Airy, Philadelphia, I was delighted to find a series of eight
or more specimens collected at Anglesea, N. J., late in July (21st),
and early in August (4th). They were taken at sugar, most of
them are females, and all are in very fair condition. None of the
specimens are quite as red or quite as well marked as normal ligata,
though coming from Texas, at least one of the examples would pass
as such without question. But, on the other hand, in the four ex-
amples now before me there is one that agree perfectly with L.
rimosa Grt., as represented in an example from Kittery Point,
Maine, kindly sent me by Dr. Thaxter. L. rimosa was described
in the Can. Ent., xiv, 216, 1882, and must be referred as a synonym
of Jiabilis. The relation of the latter species to ligata yet remains
to be determined.
AMERICAN LEPIDOPTERA. 197
Neleueania pra'graeilis C4rt., Bull. U. S. Geol. Surv.. iii. 119, 1877.
Mr. Henshaw has determined that the specimen labelled Helic-
phila gracillima, type in the Cambridge collection is really the type
of prcegracilis and has so recorded it ; I have no doubt correctly.
Leiicania rufostriga Pack.
( )n the basis of a comparison made by Mr. Henshaw I omitted
this species from Leiicania in my recent revision and suggested that
my Garadrina puuctivena might be conspecific. I examined Dr.
Packard's type myself recently, and found that at least it was not a
Leiicania. It is a horribly faded specimen, and while it is no doubt
very close to C. pnactivena, I am not so certain that it is really the
same species. If material could be obtained for comparison from
Labrador, it would be an easily settled question.
Mamestra artesla n. sp. — Ground color a grayish red or purple-brown,
over a whitish base, giving a peculiar dead appearance. Head concolorous, an-
tennae whitish. Thorax with tip of collar usually whitish, and with patagia and
disc more or less whitish powdered. Primaries with the median lines lost, ex-
cept on the inner margin ; ordinary spots white marked, and the entire wing
with a more or less mottled appearance. Basal line white, more or less broken,
and sometimes a little emphasized by darker scales. T. a. line very much broken,
yet some part of it is visible in each specimen ; usually it is a sinuate brown line
through a whitish shade on the inner margin and over the submedian vein ;
sometimes there is a diffuse white line through the cell, and occasionally this ex-
tends to the costa T. p. line evenly outcurved over the cell, and a little incurved
below ; it may consist of a single or a double series of white dots, or of a whitish
shade in which a very narrow black zig-zag line appears, and it is always marked
in brown ou the submedian vein and on inner margin. S. t. line white, more or
less contrasting, irregular, broader at anal angle, rarely lost in part. Claviform
wanting. Orbicular small, round, usually consisting only of a white annulus,
rarely emphasized by an outer ring of darker scales. Reniform upright or a little
oblique, moderate in size, broad, centrally constricted, white ringed and with a
whitish central line. There is a series of white terminal dots on the veins. Sec-
ondaries soiled whitish, veins darker and with a narrow, smoky outer shading.
Beneath whitish, a powdering of carmine scales over the costal and apical region.
a more or less obvious outer shade band and a dusky discal spot ou all wings.
Tarsi annulate with white. The entire body tending to purplish, but variable in
the direction of a yellowish ground. Expands 1.40-1.76 inches = 35-44 mm.
Hab.— Glen wood Springs, Colorado, in August (Dr. Barnes);
Douglas County, Kansas, at electric light, May (Prof. Snow).
Two males and three females in good condition are before me and
I have seen other examples, mostly from Colorado. I have an ex-
ample marked "Pennsylvania," and another marked "Illinois;"
but I doubt the correctness of the labels, though I cannot disprove

them and the species may really range east I have heretofore re-
garded this species as a form of congermana Morr., and have so
named it in collections. The receipt of additional material proves
them distinct. The peculiar, dead, chalky tinge of the primaries is
distinctive of the new species, and to this should be added the much
more pointed shape of these wings.
Dr. Barnes long since suggested the separation of the Colorado
species; but I was unwilling to do so until I had better material of
congermana. Of the dull yellow shade at the apex and inner angle
of Mr. Morrison's species no trace appears in any example of artesta.
Triclkdea nova n. sp. — Ground color pale grayish luteous, with a variably
marked reddish tint. Head and thorax immaculate, save for a variable powder-
ing of black scales which are most obvious on the thoracic disc. Primaries pow-
dered with black or smoky scales irregularly distributed, so as to give the wing
a mottled and suffused appearance. The normal maculation is all present, not
contrasting, more or less broken and sometimes obscured. Basal line geminate,
usually well marked iu its entire course. T. a. line geminate, the inner part
tending to become vague and obscured ; as a whole outwardly oblique, irregu-
larly outcurved in the interspaces. T. p. line geminate, outer portion obscure,
inner part lunulate or crenulate, also tending to become lost so as to leave a series
of black venular marks emphasized by following white dots ; as a whole the line
is moderate outcurved over the cell and only a little incurved below it. S. t. line
pale, broken, irregular, sometimes emphasized by preceding darker shades and
spots, sometimes by dusky cloudings in the terminal space. A series of blackish
terminal lunules. Fringes with a dusky interline, cut with white opposite the
veins, the margins just a little notched. All the veins more or less obviously
dusky, the median vein sometimes quite markedly so. Claviform small, with a
variably evident dusky outline. Orbicular small, oval, with a darker outline, a
pale annulus within this and a dusky centre; the latter may be lacking, leaving
the en,tire spot a little paler than the ground color. Reniform large, broad, filled
with blackish, a little constricted centrally ; a pale annulus within a border of
blackish scales defines the spot at the sides, the upper and lower margins tending
to become obscure. An obscure smoky median shade baud is visible below the
dark reniform. Secondaries pellucid white at base, becoming smoky toward the
margins; more so in the female than in the male. Beneath white, powdery;
primaries with veins marked outwardly; a series of blackish venular marks rep-
resenting the t. p. line; a dark lunule, the reniform spot; while a pale s. t. line is
obvious through an outer dusky margin. Secondaries with the veius smoky, a
small dark discal spot and a narrow smoky outer border. Expands 1.40-1.52
inches = 35-38 mm.

AMERICAN LEPIDOPTERA. 199
Six examples, in fair to good condition, are at hand. The spe-
cies runs somewhat larger than those heretofore described and is
recognizable by the peculiarly mottled appearance and tendency to
a reddish tint. In the latter character it approaches decepta; in the
others it resembles antica and postica more closely. Edwardsii is
very distinct from all the others by its uniform tinge on which the
maculation is not relieved. Antica, postica and nova are close allies,
but I believe good species. With a series at hand for comparison
the differences are marked, and the male genitalia serve to empha-
size these differences. These structures were figured for edwardsii
and decepta in the Proc. U. S. Nat. Mus., xii, pi. 22, figs. 18 and 19.
Those of the other species referred to are herewith given on pi. iii,
figs. 1-12.
Sir George F. Hampson has called my attention to the fact the
Mamestra fuscolutea is a Trichoclea in structure and must be referred
to that genus. The fact was verified too late to include the results
of gen italic study here.
Tamiocampa Columbia Sm., Proc. U. S. Nat. Mus., x, 472, 1887.
This species was described out of the Neumogen collection from
specimens taken by Capt. Geddes in 1884. The material was some-
what unsatisfactory, and the generic reference was doubtfully made.
In the revision of Tteniocampid genera, Proc. U. S. Nat. Mus., xii,
1889, the relationship of the species to Mamestra was recognized,
but the balance of characters seemed then to point to Tceniocampa.
Recently, Mr. Dod sent me from Calgary a series of specimens col-
lected in July, whose relationship to Mamestra meditata was at once
apparent, but the species was marked as distinct. In looking over
the collection of the U. S. Nat. Mus., I recognized in the typical ex-
ample of T. Columbia the species sent me by Mr. Dod. A study of
the genitalia, which were compared with fig. 5, pi. xxiii, Proc. U.
S. Nat. Mus., xii, proved the identification correct and makes it
necessary to transfer the species to Mamestra. It must be M. Colum-
bia hereafter, and in the arrangement the form must stand next to
meditata.
The series of twelve examples now before me shows a considerable
range of variation ; not only in general color, but in the distinctness
of the maculation. The normal rusty Tseniocampid brown predomi-
nates, and the range is from a decidedly yellowish shading to a very

pretty pinkish tinge ; never so dark as in the eastern form. The
maculation is sometimes almost washed out; at others the primaries
are mottled and all the ordinary spots are clearly traceable. The
median lines may be nearly lost, may appear simple, or the t. p. may
be crenulated ; some forms coming so close to Tcenioeampa rufula in
the markings that a reference there appears most natural on that
basis.
Notes on the Species of FISHIA CJrt.
The genus Fishia was described by Mr. Grote in 1877, Can. Ent.,
ix, 21, with essential characters as follows: — Tibise armed; eyes
lashed; antennae of male brush-like; wing-form like Mamestra sub-
juneta; primaries widening outwardly; thorax with a posterior tuft
and the base of the abdomen strongly tufted ; fore tibise appear to
be unarmed ; tongue weak. Mr. Grote said further, in comment,
that the genus thus combined characters of Hadena with those of
Agrotis, and described E. enthea from Oldtown, Maine.
I saw this species in the British Museum collection in 1891, and
record it in my catalogue, p. 167, as one I had not previously seen.
It impressed me then as related to Hadena evelina French, and as a
Hadena with brush like antennae. For some years I have had in my
collection a species from the Province of New Brunswick doubtfully
referred under this name. In 1900 I saw the type again, recognized
its dissimilarity to my specimens and noted that the species, though
much darker, must be compared with Aporophyla yosemitoe Gr.
In 1873 Mr. Grote described Oucullia yosemitce in the Bull. Buff.
Soc. Nat. Sci., i, 113, and figured it on pi. iii, f. 3. The specimen
was defective, and later, in deference to Dr. Speyer's suggestion, the
species was referred to Aporophyla Gn. (Bull. Buff. Soc. Nat. Sci.,
ii, 309). This species does not seem to be in the Briiish Museum,
so I could make no direct comparisons.
Of Aporophyla, Lederer says (Noct. Eur., 96) that the species
have the protuberant bulging front and lashed eyes of Episema, but
not the plump; bombyciform habitus of that genus; on the contrary,
the appearance is hadeniform, as is the maculation and the stout,
well developed tongue. Thorax broad, convex, untufted, with
smooth vestiture ; abdomen without obvious tufts; legs unarmed;
antennae of male either serrated or pectinated.
The type of A. yosemitui is in the Edwards' collection, but I never
compared it with the generic characters above given.
AMERICAN LEPIDOPTERA. 201
Hadena relecina Morr. was described in the Proc. Bost. Soc. Nat.
Hist., xvii, 216 1874, and in 1882, Mr. Grote in his list of that year
referred the species to Luceria. In 1890, in Proc. U. S. Nat. Mus.,
xii, 440, I identified the species from one female example that agreed
very nicely with Mr. Morrison's description, which I quoted. There
were some slight discrepancies in what seemed to be immaterial char-
acters and I placed the species in the series Xylophasia. Other
specimens came to hand which I named relecina without further
question, until a considerable series seemed to indicate a closer rela-
tion to Aporophyla yosemitce than was suspected, and a departure
from the original description. Recently, I saw Mr. Morrison's type
in the Museum of Comparative Zoology at Cambridge, and find that
Mr. Grote was right in referring the species as an ally of burgessi,
and that through a failure to realize the meaning of Mr. Morrison's
term "gray," I had totally misidentified his species. The descrip-
tion of the maculation stands very prettily, and the form of the
ordinary spots is almost identical, as are the strongly dentate median
lines ; but in color and wing-form my relecina is totally different from
Mr. Morrison's.
This induced a renewed study of my series of specimens, and I
find that I have three males and two females that agree with both
Mr. Grote's type and with his description ; but they agree also with
Mr. Grote's characterization of Fishia, except that the tongue is not
weak. The species is certainly not an Aporophyla as Lederer de-
scribes it, and would be accepted as Hadena on superficial charac-
ters without any question. It is really a very close ally of Anytus
Grt., from which it differs mainly in the more trigonate and more
pointed primaries, in the less depressed form and in the finer, some-
what more compact vestiture. As the type of maculation is very
different and the habitus distinctive, Fishia must stand as an Agro-
tid genus with middle and hind tibise spinose ; the hind tibiae sparsely
armed and chiefly between the usual spurs. The thoracic crest is
distinct and is divided anteriorly and posteriorly.
Enthea is the type and is described as coal black, with the mark
ings velvety black. This form is not represented in the series be
fore me.
Yosemitce is dark ashen gray, very even in color, with the lines
black and well defined. The secondaries are gray, powdery, whit-
ish at base in the male, darker throughout in the female. The

characteristic maculation on the primaries is : a slender, somewhat
curved black basal streak ; strongly dentate, single median lines,
approaching each other in the submedian interspace and connected
by a large claviform, the tip of which actually touches the t. p. line ;
a series of inters paceal black dashes in which the s. t. line is marked
by white dots or scales ; a long, narrow, obliquely decumbent orbicu-
lar ; and a large, outwardly defined reniform. My specimens are
from Calgary and from British Columbia. The former are from
Mr. Dod, dated September 20th and October 11th ; the latter are :
1 from Roundthwaite, the other of Capt. Geddes collecting without
definite locality.
Exhilarata is a bright whitish gray species in the male, the macu-
lation of the primaries clearly written, the secondaries purely white.
In the female the ground is more fuscous, powdery, the maculation
all obscured and smoky rather than black. The secondaries are
smoky fuscous throughout. The marked difference between the
sexes and the pure white secondaries in the male will distinguish this
species from yosemitce. My series consists of three males and four
females: Glenwood Springs, Colorado, late September and early
( >ctober (Dr. Barnes); Pullman, Washington, October 10th to 15th
(Prof. Piper).
The new species is characterized as follows :
I'i>hi;i e.vliilarata n. sp. — Male. — Pale ashen gray, powdery. Head
darker, with a blackish frontal line. Collar with a narrow black line across the
middle. Patagia with black submargiual lines. Basal line not obvious. A black
basal streak running into the deep outward sinus of the t. a. line. T. a. line sin-
gle, black, slender, broken, strongly dentate, the tooth in the cell touching the
margin of the orbicular, that in the submedian interspace reaching nearly half-
way to the inner angle. T. p. line black, single, slender, dentate, more or less
broken, most conspicuous in the submedian interspace where it curves inwardly,
is preceded by a black shade and followed by a white one. S. t. line white, punc-
tiform, irregular, marked by linear or sagittate preceding and following black
shades, forming a diagonal series from the black shade in the submedian inter-
space to below the apex. Claviform broad, extending across the median space,
black margined. Orbicular oblique, oval, a little more whitish than ground.
Reniform concolorous, moderate in size, more or less completely outlined in
black.
Female. — Maculation as in the male, but everything more obscured, less de-
lined, and the entire ground powdery and fuscous tinged.
Expands 1.40-1.60 inches = 35-40 mm.
Hub. — As stated above.
AMERICAN LEPtDOPTERA. 203
Paclinobia roOMta n. sp. — Ground color rusty red-brown. Head and
thorax immaculate; with thin, divergent, hairy vestiture. Primaries whitish
powdered over the costal region to the t. p. line, the ordinary markings well
written. Basal line single, brown, clearly marked across the whitish costal
region. T. a. line brown, preceded by a white shading, outcurved in the inter-
spaces, with strong inward dents on the veins. T. p. line blackish brown, fol-
lowed by white scales, feebly crenulate, only a little outcurved over cell, some-
what incurved below. S. t. line marked by an irregular s. t. shading against the
uniformly paler terminal space. A broken, black terminal line. From the base
below median vein runs a narrow yellowish streak broken at the t. a. line, and
continued beyond it as a filling to the small, pointed claviform which is diffusely
brown bordered. The cell between and before the ordinary spots is deep velvety
brown. Orbicular small, irregular, quadrate, white filled, open to the costa, out-
lined by the deep brown shade elsewhere around it. Reniform narrow, oblong,
irregular, a little constricted, oblique, marked by white scales about a central
yellow shade, outlined by dark brown scales. Secondaries smoky over a chrome-
yellow base, powdery. Beneath smoky powdered over a yellowish base, the
costa tinged with carmine. Both wings with a diffuse, smoky outer band and a
somewhat lunate discal spot. Expands 1.68 inches = 42 mm.
Hab. — Nushagak, Alaska, August 28, '01, McKay, collector.
One male, in fair condition, from the U. S. National Museum.
The antennae are serrated and bristled, and the species thus belongs
with carnea, from which it differs in the lack of all gray shadings,
in the completely defined median lines, in the white marked differ-
ently shaped ordinary spots and in the wing form.
Carneades rumataiia n. sp. — Head and thorax luteous gray; head
paler in front and with a dark interantennal line; collar with a median and ter-
minal black Hue, between which a broader brown band crosses the ground ;
patagia with a black submargin and a white line just behind the collar, Prima-
ries smoky luteous; costal and subcostal veins, but not the costa itself, white to
the end of the cell ; median vein white; a bright yellow bar from the claviform
to the t. p. line; s. t. line indented on veins 3 and 4 only; apex pale. Basal line
marked as an inwardly oblique black bordered yellow line in the submedian
interspace only. T. a. line geminate, marked by black dots on the costa, obsolete
over the costal area, yellowish, with black margins below the median vein ; only
a little outcurved in the submedian interspace; with a longer outcurve below
vein 1. The latter is black, with a uarrow yellowish border on each side. T. p.
line marked by geminate black spots on the costa, white and abruptly bent over
the upper angle of cell, thence a somewhat irregularly lunulate broken black
line, a little sinuate, but on the whole, nearly parallel with the outer margin. S.
t. line yellow, very distinct, except where it is cut by the pale apical area ; very
even except on veins 3 and 4, on which it is moderately indented. A lunate
black terminal line. A distinct yellow line at the base of the fuscous fringes.
The terminal space is evenly dark except at apex. The s. t. space is paler at the
t. p. line, but darkens toward the s. t. line except on veins 3, 4, (5 and 7 which are
black lined in a whitish shading. The median space is a little darker in the

cell. Claviform black margined, coucolorous, extends about half-way across the
median space, a bright yellow bar completing the distance. Orbicular small,
oval, oblique, narrowly defined by black scales and a white annulus ; centre
ltiteous. Reuiform upright, oblong or a little lunate, narrow, black edged, white
ringed, centre luteous with narrow smoky lines. Secondaries whitish, the veins
smoky, a smoky extramedian line, beyond which the wing is more or less smoky,
a smoky discal lunule; fringes white. Beneath, primaries smoky gray, except at
the margins which are paler. Secondaries a little paler than above, but similar
in maculation ; fringes white. Expands 1.04-1.28 inches = 26-32 mrn.
Hub. — Volga, South Dakota (Truman j ; Calgary, Alberta, Aug.
23rd (Dod).
Sixteen males and one female, nearly all in very good condition.
The species belongs obviously to the quadridentuta series, but is quite
distinct from all the species by the dark margined secondaries, which
give it a marked resemblance to some species of Oncocnemis. The
single example from Mr. Dod, numbered 10, has been in my collec-
tion for a long time without a definite place; with the South Dakota
material at hand it finds a natural home. It is likely that Mr.
Truman had this form mixed with niveilinea in which the secondar-
ies are entirely white. The specimens sent me were included in a
miscellaneous lot of unspread supposed duplicates and have been
but recently brought to light.
Agrotipliila molilalia Morr., Ann. Lye. Nat. Hist. N. Y., xi, 95, 1875.
This name was referred by me as a synonym of A. staudingeri
Moeschl., after comparing Moeschler's typical specimen with the
Morrison specimen marked type in the Tepper collection. I have
still a photograph made from Moeschler's type ; but have not sue
ceeded in securing specimens. In looking through the collection of
the Museum of Comparative Zoology recently I found another speci-
men of Agrotis montana Morr., marked "type," which I recognized
as belonging to the species described as rigida by me. Comparing
this example with Mr. Morrison's description, it is evident that it
was the one actually used in delineating the characters because it
was the better of the two before him. To the courtesy of Prof.
Rufus H. Pettit of the Michigan Agricultural College, I owe a
sketch of the Tepper type which confirmed my previous conclusions
and proved that Mr. Morrison had two distinct species before him
when he wrote, but drew his description from one of the examples-
only. The Cambridge specimen is therefore the real type of Mr.
Morrison's name which must be restored to the list, and my rigida,
Trans. Am. Ent. Soc, xviii, 133, must fall in as a synonym.
AMERICAN LEPIDOPTERA. 205
A case of this kind is perhaps the most potent argument for hav-
ing only a single example as an actual " type."
Incidentally, the species standing as Agrotiphila velata Strck. in
Dr. Dyar's list is wrongly placed. Dr. Strecker described the spe-
cies as an Agrophlla, and the name should have been listed under
Spragueia on p. 215.

vestiture; eyes small, round; tongue wanting; antennae of the $
lengthily bipectinated, the branches setose; vestiture fine hairy,
divergent. Thorax stout, clothed with very dense long woolly ves-
titure forming no tuftings; legs stout, all the tibiae spinose ; anterior
abbreviated, broad, obliquely terminated, inner angle with a long,
stout, curved claw, outer angle with a slighter, shorter claw, outer
edge with two claws as long and as stout as the one at the angle.
Abdomen un tufted. Primaries rather short and broad ; secondaries
rather large, proportionately ; venation normal ; vein 5 of the sec-
ondaries weak and well removed from 4 on the cross- vein.
The characteristic features of this genus are its Bombycoid
appearance, emphasized by the woolly vestiture, retracted head,
lengthily bipectinated antennae and lost tongue, combined with the
spinose tibiae and very characteristic armature of the anterior pair.
Vluili'iitu elingua n. sp. — Head and thorax white, with a pinkish tinge,
which becomes marked on the thoracic disc. Primaries with a pinkish flush
over a very pale yellowish base, and mottled with a powdering of black scales.
The basal line is geminate, blackish, punctiform. T. a. line single, irregular,
diffuse, blackish, broken, with a long outward loop in the submedian interspace
which replaces the claviforiu. T. p. line single, blackish, diffuse, oblique over
the costal region, lost over the cell, lunulate below the median vein. S. t. line
a series of dusky points in the pale area. S. t. and terminal spaces more or le.-s
black powdered. There is a series of vague terminal dots. The fringes are
pinkish, cut with white. Orbicular round, white, obscurely outlined by scat-
tered black scales. Reuiform not defined ; a sort of pinkish, upright constricted
line in a whitish cloud. Secondaries whitish at base, becoming smoky at the
base of the white fringes. Beneath, primaries faintly yellowish ; secondaries
white; breast white, woolly; tarsi brown, ringed with whitish. Expands 1.20
inches = 30 mm.
Hab. — Phoenix, Arizona, November 10th and 19th.
Two male specimens collected by the late Dr. Griffiths. Both
examples have been papered and are somewhat flattened ; one is a

little torn in addition ; but the other is in very fair condition. The
generic characters will identify the species which may be associated
with a small group of heavily built moths surrounding Thyreion
and Fala.
LYTHRODES n. gen.
Head closely applied to the thorax, yet not retracted ; front pro-
tuberant, the centre depressed, crateriform, this depression medially
divided by an acute vertical plate which extends beyond the crater
nearly half its diameter ; palpi very small, not extending beyond
the rim of the shield which forms the lower margin of the head ;
tongue moderate only and perhaps not functional ; eyes moderate in
size, hemispherical but not prominent; antennae simple; vestiture
thin, hairy, divergent. Thorax rather small, clothed with thin,
hairy vestiture, which forms no tufts; collar and patagia not re-
lieved ; legs rather stout, tibiae unarmed, except for the usual spurs,
the tarsi somewhat shortened, with unusually large terminal claws.
Abdomen smoothly scaled, untufted. The wings are rather large
in proportion to the body ; primaries trigonate, costal margin
slightly curved, outer margin even, regularly arquate, inner margin
sinuate; venation normal; secondaries with vein 5 only a little
weaker than the others, from the cross-vein near to its middle.
The characteristic features of the genus are its peculiar frontal
structure, the short stout tarsi, otherwise unarmed legs and the sinu-
ate inner margin of the primaries. It may be associated with Cha-
maclea Grt.
Lythrodes radial us n. sp. — Head and thorax white, with a faint yel-
lowish tinge ; abdomen white. Primaries creamy white, with bright almost car-
mine red streaks as follows: two short apical streaks; two occupying the inter-
spaces between veins 4-5 and 5-6, respectively, for their whole length ; one fill-
ing the interspace between veins 2 and 4; one extending from base beneath vein
2 to the outer margin ; two short basal streaks above and below vein 1. Fringes
whitish, cut with black opposite the interspaces. No median lines and no ordi-
nary spots. Secondaries white, with a faint yellowish tinge. Beneath whitish,
primaries with the disc a little darker, the markings of the upper side faintly
reproduced. Expands .80-.88 of an inch = 20-22 mm.
Hub. — Yuma County, Arizona.
This pretty little species is one of those collected by Mr. Hutson
in the Colorado desert, and is represented by two females in good
condition. It is altogether unlike any of our other described spe-
cies, and its only close allies are the species next to be described.
AMERICAN LEPIDOPTERA. 207
Lythrodes venatus n. sp. — Head and thorax pale, almost crearny yel-
low ; abdomen nearly white. Primaries pale yellowish along the costa and inner
margin, else earmineous, with all the veins relieved in pale yellow, the light
color expanding somewhat toward the outer margin. Fringes white, cut with
blackish opposite the interspaces. There is a whitish, indefined spot in the cell
representing the orbicular; but none other of the ordinary markings are present.
Secondaries white, with a faint yellowish tinge. Beneath, primaries with disk
smoky reddish, the margins yellowish ; maculation of the upper side faintly re-
produced. Secondaries as above. Expands 1 11 inches = 28 mm.
Hub. — Santa Fe, New Mexico, in July, at light.
One female in rather poor condition from Prof. T. D. A. Cocker-
ell, numbered 3783, and there is a similar specimen from the same
source in the collection of the U. S. National Museum. The species
is much larger than radiatus, and, whereas in the latter, the main
color is yellowish and the streaks are red, in venatus red is the domi-
nant tint from which the yellow veins stand out in some relief.
Lytlirodes discistriga n. sp.— Head and thorax whitish ; head with
transverse rusty brown frontal and vertexal lines; thorax with a central and
two lateral longitudinal rusty brown lines extending from base of collar to base
of disc; patagia brown mottled. Primaries whitish, all the veins lined with
rusty brown and an additional line through the submediau interspace. In the
basal area there is a yellowish shading, and the veins are more heavily marked.
At the end of the submediau its branches are shaded with brown in the inter-
spaces, and at the apex the veins are also more heavily marked. Secondaries
ocher-yellow, glistening. Beneath, primaries brown on the disc, paler outwardly
with the veins relieved ; secondaries about as above.
Expands .8-1.00 inch = 20-25 mm.
Hab. — Walter's Station, California, in April ; Southern Arizona,
April 1-15.
Two male examples; the California example, taken by Mr. Hut
son, is nearly perfect and is the smaller; the Arizona specimen is
from Mr. Poling and is somewhat defective. Both are from what is
practically the same desert area ; but the difference in size between
examples of the same sex is unusual and a little puzzling. The
abdomen is of the same yellow shade as the secondaries, and this,
with the maculate thorax and rusty instead of red streaking will
easily separate the species from the preceding.
Pseiidotauiila carniinatra n. sp.— Head black, the protuberant front
clothed with dense. whitish hair. Thorax blackish, with carmine scales and
whitish hair intermixed, the collar darker inferiorly, else forming no distinctive
maculation. Primaries with a carmine shading over a dull, smoky though pale
luteous. The scales are a little metallic or coppery, and the tint changes soine-

what according to the angle of vision. The darkest part of the wing is at the
base, extending along the costal region to the apex, and then along the fringes to
the hind angle; the lightest part is in the cell on each side of the reniform.
Basal line smoky, diffuse, from the basal third of costa, a little curved inwardly
to reach the inner margin well within its basal third. T. p. line smoky, diffuse,
followed by a paler shading, evenly outcurved over the cell and a little incurved
below. No. s. t. line. Fringes blackish at base, tipped with white. Orbicular
wanting. Eeniform large, oval, iudefined, smoky. Secondaries black, with
whitish fringes. Beneath, primaries with upper half of basal space, a large dis-
cal spot, an extra median band and all of terminal space black, else white; sec-
ondaries black, with white fringes and sometimes with a narrow white submar-
ginal line; the body parts are clothed with whitish. Expands .60 of an inch
= 15 mm.
Hab.— Colorado, 6000 feet.
Two males and two females in good condition. The specimens
came to me several years ago from Mr. David Bruce, but were, I
think, collected by Mr. Mason. I have neither date nor accurate
locality. The species is smaller than its congeners, and easily dis-
tinguished by the black secondaries and carmine shaded primaries.
IVIelicleptria kasloa n. sp.— Head, thorax and abdomen black, with a
clothing of thin yellowish or greenish hair that permits the ground color to
appear. On the abdomen the vestiture forms fringes at the edges of the seg-
ments, giving a ringed appearance. Beneath, on body and legs the vestiture is
much more dense, longer, and the whole appears whitish or very pale yellow.
Primaries with the basal, s. t., and most of the terminal space olivaceous, with
an admixture of black scales. The median space is whitish or pale yellow, with
dusky clouds on the costa and inner margin. The median lines are marked only
by the contrast between the median space and those on each side of it. T. a. line
from costa across the cell about one-fourth from base, then outwardly bent almost
to the middle of the wing and incurved to reach the inner margin at about its
basal third. T. p. line very evenly and moderately Insinuate. S. t. line yellow-
ish or whitish, sharply limited in the dark s. t. space, somewhat diffuse out-
wardly ; in course it is irregular, and sends in a long dent opposite the cell, con-
stricting and nearly dividing the s. t. space; below that rather evenly bisinuate.
Fringes dark, cut with yellowish opposite the interspace. Ordinary spots large,
solid, of the dark ground. Orbicular round ; reniform broadly kidney shaped.
Secondaries black, with a whitish disc, which is very much narrowed by the
large black discal spot ; there is also a very small yellowish band near the middle
of the outer margin. Fringes whitish. Beneath whitish, the lower half of basal,
and all of the s. t. space and the large ordinary spots black; secondaries with
inner margin, a large discal spot and an abbreviated outer band, black. Expands
.96-1.00 inch = 24-25 mm.
Hab. — Kaslo, British Columbia, June 7th and 26th.
Three females, in good condition, from Mr. J. W. Cockle. One
of the examples is bred and this is somewhat lighter in color,

appearing as if there was a thin film of whitish over the insect,
which disappears after even a brief flight. The species is quite a
well marked one and seems to conflict with none other of the genus.
Notes on ACOWTIA <►< lis.
To the courtesy of Dr. William Barnes I owe a series of speci-
mens from his collection, including also some that were collected by
or for Mr. O. C. Poling. This material has enabled me to decide as
to the standing of some forms that had been doubtfully set aside,
and it added some forms undoubtedly different from anything that
1 had previously had under observation. The increase in the mini
ber of species has been quite unexpected, and indications point to
a yet greater number. All the separations made have justified
themselves, and the range of variation, though considerable in cer-
tain directions, seems to move within tolerably well defined lines.
The exact standing of the species cited by me under elegantula
Harv. is yet open to question. Of arizona and seminivealis I have
compared the types and their identity is unquestionable. I am not
so sure now that elegantula is really the same species. A consider-
able series of the arizonae, form is now at hand and shows so much
variation that I have been tempted to believe that there was more
than one species; but none of this variation runs toward elegantula
which is clearly separable, though nearly allied in type of macula-
tion. Elegantula comes from Nevada, and I have no material from
that region for comparison. Under the circumstances arizona' must
be restored to rank as a species. As to semiopaca, Mr. Grote has
himself made this a synonym of elegantula. I have no material
from the type locality of tins species (Montana), therefore cannot
speak as to the correctness of the reference; it is ;i probable one,
however, as the faunal region is the same.
Tornaeontia altera n. sp. — Head, thorax and abdomen white, immacu-
late. Primaries white to the middle, save for a gray shading at base ; olivaceous
gray or brown outwardly. The basal gray shade extends over the costal region,
broken by the white basal line to the t. a. line, which is white and defined by
the gray shading which extends across the wing over its course. The shadings
are not at all prominent and much lighter than the outer parts of the wing. The
outer limit to the pale space is formed by the median shade which is olivaceous
gray on the costa, a little oblique to the cell in which it is cut by a pale ray that
extends to the reniform ; below the cell it is defined by a rich brown shade which
forms a band of moderate width and fades into a bluish gray. The t. p. line is

incepted by a gray costal spot, followed by a white patch which extends obliquely
iu to the reniform ; over the cell the line is barely traceable, and below that it is
lost. S. t. line white, irregular, tending to become broken. Terminal space cut
with white on the veins and tendiug to become white powdered. A broken ter-
minal line of black scales. Fringes long, white, with an olivaceous line at base,
and olivaceous spots at apex, above the middle of the. margin and at the hind
angle. The orbicular is a minute black point. The reniform is round or nearly
so, olivaceous gray, partly edged by black scales, white ringed. Secondaries
white, becoming smoky at the outer margin ; fringes white. Beneath, primaries
smoky, the costal and outer margins white ; secondaries white, immaculate. Ex-
pands .92 inches = 23 mm.
Hab. — Southern Arizona (Poling) ; Hot Springs, New Mexico,
7000 ft, alt. ( Hulst).
One male and one female, both in fair condition. The frontal
process in this species is shorter and more obtuse than in the other
described species, but is obvious and justifies the reference to this
genus, in which it is thus far unique in having the head and thorax
white. Superficially it resembles candefacta at first sight, differing
at once, however, by the white secondaries.
Toi'iiacontia tripartita u. sp. — Head deep sable brown. Thorax white,
collar brown tipped ; the vestiture of the disc is defective iu the specimen before
me, but apparently the patagia are edged with brown. Primaries white, with a
vague bluish tint, the markings bluish gray. The upper half of the wings is
chiefly white; the lower half is mostly gray; the space between the 7iiedian and
t. p. line below the cell forming the darkest portion of the wing. All the usual
lines obvious. Basal line forming a brown spot on the median vein. T. a. line
leaden gray, diffuse, and incomplete over the cell, deeply incurved, black, pre-
ceded by a white line from the median vein to the inner margin. The median
shade line is marked by a gray costal spot, is lost through the cell, black, parallel
to the t. p. line from the median vein to the inner margin. S. t. line marked by
a gray s. t. shade which contrasts with the white terminal space ; in course only
a little irregular. A black, lunate terminal line, narrowly cut on the veins.
Orbicular a small round dot. Reniform small, a little irregular, gray, the sides
edged with black. Secondaries dull white, with a faint smoky yellowish tint.
Beneath, primaries blackish, the margins yellowish, the reniform black; second-
aries as above. Expands 1.00 inch = 25 mm.
Hab. — Wilgus, Cochise Co., Arizona.
One female in fair condition, from Dr. Barnes* collection. The
species is allied to megocula, but is more white, with all the usual
markings present, and the reniform small, irregular. The chisel-
like projection on the front is broad and well marked. On the sec-^
ondaries the venation is as in its allies.
Conacoill ia orba n. sp. — Head and thorax creamy white; vertex and
disc a little smoky. Abdomen yellow. Primaries creamy white along the costa

and somewhat less than half the upper portion, interrupted by a narrow band at
t. a. line, a broad band at t. p. line over reniform, and by an irregular large blotch
before the s. t. line; apex also dusky. The lower half or more is smoky gray to
the s. t. line, leaving the hind angle white. Most of the s. t. space is white, ex-
cept on the costa. The terminal space is mottled with golden brown, and there
is a broken black terminal line. The fringes are smoky, twice Gut with creamy
on the outer margin and creamy at the hind angle. A somewhat obscure band
of golden brown scales begins at the dark s. t. spot on costa, curves inward to
include the reniform and then downward to the inner margin at its middle T.
a. line marked as a gray band over the pale upper half of the wing. T. p. line
marked by a broad costal band and then lost until it re-appears as a broken
blackish outer edging to the golden brown band. S. t. line marked as a narrow
white line between the dark apex and s. t. patch on costa, then lost in the creamy
s. t. space. The orbicular is a distinct round gray spot of moderate size just sep-
arated from the dusky lower portion of the wing. The reniform is a larger
round spot incompletely white ringed and not completely separated from the
dusky costal patch just above it, or from the dark inferior portion of the wing.
Secondaries an even, pale, glistening smoky yellow. Beneath, primaries yellow,
the disc smoky and with a discal spot ; secondaries very pale yellow, with darker
outer border. Expands .84-1.04 inches = 21-26 mm.
Hab. — Huachuca Mountains, Arizona.
Three females in fair condition, from Dr. Barnes. The species
is allied to angustipennis in general appearance and type of macula-
tion, but differs obviously in the pale thorax and the distinct orbicu-
lar. There are other marked differences, but these are the most
apparent and render the new form recognizable at a glance.
Conacoiltia huachuca n. sp. — Head and collar creamy white, disc of
thorax leaden gray ; head with an admixture of gray scales on the vertex and
on the front. Primaries creamy white along the costal region nearly to the s. t.
line and embracing all above the median vein. Along the inner margin, starting
not quite at base, and extending to the s. t. line, is a deep gray shading, very-
jagged at its upper margin, nearly or altogether cut by an obtuse extension of
the white shade at its middle; indented or quite crossed by a narrow pale thread
at the place of the t. a. line, and by another, even more irregular beyond the t.
p. line. There is an apical gray patch, through which the s. t. line is obvious,
and a series of three patches along the outer margin, which also extend over the
fringes. The median lines are traceable through the pale region of the wing
as lemon-yellow lines. Orbicular wanting. Reniform a small yellow dot encir-
cled by the vaguest kind of a yellow annulus. There is a series of black termi-
nal lunules. or a broken black terminal line. Secondaries white, with a faint
yellowish tinge. Beneath, primaries distinctly yellowish, with maculation of
upper side feebly reproduced ; secondaries white. Expands 1.08 1.12 inches =
27-28 mm.

general type of maculation ; but the secondaries are nearly white
instead of smoky ; the primaries are whiter, and have the dark area
along the inner margin broken and irregular; the thoracic disc is
leaden gray instead of brown, and, finally, the frontal process of
the head is umbilicate or navel shaped, with an obvious rim sur-
rounding the roughened protuberant centre.
Acontia alessandra n. sp.- Head and thorax white; front protuberant,
with a gray transverse band. Abdomen yellowish. Primaries white from base
to beyond middle, interrupted on the costa by an oblong, smoky gray patch at
the normal inception point of the t. a. line. At the inception point of the t. p.
line another oblong bar separates off a quadrate white spot which extends to the
s. t. line. Outer portion of wing olivaceous gray, mottled with black and brown
scales. In this dusky area there are traces of a dentate black t. p. line and of a
very irregular and incomplete pale s. t. line; but all is broken and obscured.
There is a black, interrupted terminal line and the. fringes have a blackish cloud
opposite the cell and at inner angle. Orbicular wanting. Reniform nearly
round, blnckish, absorbed in the edge of the dusky outer portion of the wing.
Secondaries white, yellowish tinged along the outer margin. Beneath, pale
yellowish, with the maculation of upper surface faintly reproduced on the pri-
maries. Expands .76-. 88 inches = 19-22 mm.
Hub. — Stockton, Utah, in October (Franck); Huachuca Mts.,
Arizona (Barnes); Shovel Mt., April and July, Kerrville, and
Black Jack Springs, Texas (Coll. div.).
Six specimens representing both sexes in good or fair condition.
The species belongs to that series in which a quadrate white spot is
separated on the costal region before the apex. It is allied to
quadriplaga, but is white at the base and to or beyond the middle.
There appears to be no obvious difference between the sexes and
there is no species with which it is liable to be confused.
Icontia disconnect a u. sp. — Head and thorax gray ; collar more or less
broadly white; disc with metallic scales. Primaries white above the median
vein and along costa to the s. t. line. A dark, brown gray shading from base
below median vein to the t. p. line, deeply indented or entirely cut by a white
tooth from the middle of the median space. The apex is brown, and from this
an oblique shading of olivaceous, gray and metallic scales extends toward the
dark area along the inner margin without, in any case before me, quite bridging
the gap. The area about the hind angle white. There is a broken hlack termi-
nal line, and the fringes are largely leaden gray. 8. t. line very incomplete,
white, variably marked by dusky shadings from the costa to the middle of the
wing, thence lost. Orbicular wanting. Eeniform vaguely marked in one speci-
men only. Secondaries white, with a faint yellowish tinge, and with a narrow
smoky outer edging. Beneath, primaries yellowish, the maculation of the upper
surface faintly reproduced; secondaries white or nearly so. Expands .94-1.04
inches = 24-26 mm.
AMERICAN LEPIDOPTERA. 213
Hab. — Huachuca Mts., Arizona (Dr. Barnes).
Four males in good condition. This species hears an aggravating
resemblance to Conacontia huachuca; but while the front of the
head is prominent and somewhat inflated, there is no umbilication
and no projecting rim. There can be no question of a sexual differ-
ence, because all the examples of both species are males. Within
the genus to which I have referred it, the nearly ally is major, which
is much larger and has decidedly yellowish secondaries.
Acoutia liuif a n. sp. — Head and thorax white ; head with a protuberant
front; sometimes almost tuberculate. Primaries white to the middle, and the
white continues along the costal region to the s. t. line, broken only by a yellow-
ish or gray costal spot at almost the middle of the costal margin. A leaden gray
area begins at tbe middle of the inner margin, reaches nearly to the inner angle
and narrows a little toward the median vein on which it is obtusely rounded,
leaving the round, leaden gray reniform free. A yellow shade extends into the
cell before the reniform, and may or may not connect with the gray patch on the
costa. The terminal space is dusky, gray or yellowish from the apex to the mid-
dle of the outer margin, and in some specimens it continues almost to the hind
angle and invades the s. t. space, indicating an irregular, broken s. t. line. There
is a white terminal line before a series of black interspaceal marks. The fringes
are gray at base, tipped with white. Orbicular wanting. Reniform round, leaden
gray, white ringed or entirely surrounded by white. Secondaries blackish
tinged, paler basally, the fringes white. Beneath, primaries blackish, with a
yellow tinge along the costa, secondaries white. Expands .60 .80 inches = 15-
20 mm.
Hab — Kerrville, Texas, Huachuca Mts., Arizona, in April (Dr.
Barnes) ; Southern Arizona (Mr. Poling).
Three males and five females, all in good condition. The species
is similar to binoctda in general appearance, but is smaller through-
out. The secondaries have a blackish tinge and the terminal area
is more evenly gray. In binocula there is a continuous band from
the broad gray area which rests on the inner margin to the apex,
which partly envelopes the reniform, but leaves the terminal area
free. In huita this large gray area is not continuous and is com-
pleted below the reniform. The gray shading extends from the
apex along the outer margin, and if the two shadings are at all
connected it is by yellowish shadings. There is also a resemblance
to candefacta, especially as the dusky secondaries of that species
offer a similarity; but here the absence of all gray markings in the
basal area, joined to the separation of the gray shadings, affords a
distinctive character.

Euelidia dyari n. sp.
This is a new name to designate the species which Dr. Dyar mis-
took for intercalaris Grt., when, in 1898, he determined that there
were two allied species. Mr. Grote's description is peculiarly indefi-
nite and applies with almost equal force to two forms with practi-
cally the same pattern of maculation. I had never seen the two
together and may have put the same name on both at different times.
Apparently Dr. Dyar accepted the specimen labelled intercalaris
in the U. S. National Museum as the true species, and described as
diagonalis the form differing from it. Prof. F. H. Snow recently
sent me, among other material for determination, a specimen of the
supposed intercalaris, and, as he collected the material for the origi-
nal species, I returned the example unnamed, with the request that
he compare it with his type material. This he did, and was good
enough to send me one of the two typical specimens from the
Museum of the University of Kansas. This proves to be diagona
lis Dyar, which is therefore a synonym of intercalaris Grt., and
leaves an unnamed form. Dijari is that form of Euelidia in which
a broad pale band curves upward from the hind angle to connect
with the equally pale reniform. Intercalaris is that form in which
the bar from the hind angle is oblique and reaches the median vein
well beyond the reniform. The synonymy stands:
E. intercalaris Grt.

intercalaris J Dyar.
Isogona reniformis a. sp. — Ground color a very pale gray, with a yel-
lowish admixture, tending to ashen. Head and collar rusty yellow-brown. Tho-
racic disc like primaries. Primaries with all the veins pale through the dark
markings of the wing; reniform and most of the s. t. space contrasting deep
bronze-brown. Basal line indicated by scattered blackish scales. T. a. line sin-
gle, deep brown, broken, marked by a triangular spot on costa, variably evident
below that. T. p. line, single, brown, linear, broadly broken on each vein, rather
squarely exserted over the cell and a little incurved below. S. t. line of the
ground color, narrow, well marked, irregularly sinuate, dislocated on veins 5 and
6, emphasized by a preceding dark shade and a much narrower following one.
A series of black terminal lunules, and a yellow line at base of fringes. Orbicu-
lar a deep brown round dot or spot of variable size, and it may be altogether
wanting. Reniform large, brown, with a little curve, narrowly bordered with
pale scales. Secondaries ranging from yellowish to smoky, the outer margin a
little darker, a discal lunule obvious in some specimens. Beneath, very pale
yellowish ; primaries with a discal cloud. Expands .80-. 92 inches = 20-23 mm.
AMERICAN LEPIDOPTERA. 215
Hab. — Hackley, Texas, in April.
Three male and two female examples in poor condition, through
Mr. George Franck. As compared with natatrix (tenuis) this is
much smaller, with shorter, more trigonate primaries, in which the
outer margin is not obviously angulated. The palpi are also shorter
and the markings are quite characteristic. The species seems to be
locally common, and specimens are in several collections as tenuis —
through my fault.
Yrias albiciliatus n. sp. — Head and thorax pale pink ; like a pink flush
over a white base. Primaries ranging from pink at base to brick-red in the ter-
minal space; outer half of basal space and all of the s. t. space leaden gray ; alto-
gether a very pretty species, with well defined contrasts and markings. Basal
line geminate, gray, included space brick red, forming the inner limit of the gray
fascia that extends to the t. a. line. The latter is geminate, inner defining line
blackish, outer line narrow and brown, included space brick red ; as a whole out-
wardly oblique and only a little irregular. T. p. line geminate, inner line very
narrow, gray, outer line darker, merging into the dark s. t. space, included shade
brick red ; as a whole the line is squarely exserted over the cell and nearly
straight from below the reniform to the inner margin. S. t. line irregularly and
deeply sinuate, at two points almost touching the outer margin, defined by the
difference in color between the leaden gray s. t. and brick red terminal spaces.
On each side of this leaden gray band there are white dots on the veins. There
is a festooned terminal line, beyond which, on the incurves, are red tunnies, and
on the outcurves blackish gray spots at the base of the very long whitish fringes.
A quadrate gray blotch at the middle of the costa indicates the beginning of a
median shade which is marked only by a few gray scales to vein 1, below which
it is distinct to the margin. The orbicular is wanting in the specimen. Reniform
indicated by a few gray scales forming a very fragmentary outline. The pale
pink of the median space becomes brick red in the square exsertion of the t. p.
line. Secondaries whitish at base, leaden gray beyond the middle, the inner
margin of the dark area irregular. Fringes long and white. Beneath, wings
white at base, with a broad blackish outer band ; fringes white. Expands .84 of
an inch = 21 mm.
Hab. — Yuma County, Arizona (Hutson).
A beautiful little species, represented by one very good female
specimen. The species is not really an Yrias, but it resembles that
genus in general form, and may remain here until further material
makes a better reference possible.
Yrias strigalis n. sp. — Ground color a smoky yellowish brown, with an
admixture of metallic bluish gray scales. Head darker, seal-brown. Collar
intermediate in color between the head and thorax, which is of the same color
as the primaries. Wings transversely strigate by alternate rows of smoky and
gray scales over which the maculation is obscurely writen in smoky brown. Pri-
maries without contrasts; a blackish apical spot, outwardly defined by a yellow

line, is the most conspicuous feature. Basal line geminate, irregular, as a whole
upright or even a little oblique inwardly; the included shade yellowish, outer
defining line most obvious, diffuse. T. p. line geminate, inner line luuulate, in-
cluded space yellowish ; a diffuse shading over the entire line breaks up this in-
cluded space into yellowish lunules; in course the line is evenly outcurved over
the cell and a little incurved below it. Median line geminate, smoky, included
space paler, curved over the reuiform and as a whole intermediate in course be-
tween the ordinary lines. S. t. line yellowish, incurved in the interspaces, out-
wardly toothed on the veins, preceded by a smoky shade line. Outer margin
indented on the veins, rounded over the interspaces. A smoky terminal line
follows the margin, and running in a little on the veins meets the teeth from the
s. t. line, the terminal space being thus divided into a series of smoky circles.
The tendency is to a somewhat darker, more bluish tinge in the s. t. space; but
this is not a prominent or even a constant feature. Orbicular a smoky, round
spot of moderate size in a yellowish areole. Reniform a large, irregular, inde-
fined smoky blotch, followed by a yellowish shading. Secondaries with the
maculation bands and lines of the primaries continued across them, but some-
what less obviously. The terminal space is broader and the division is into ovals
rather than circles. There is no discal spot. The fringes are long, follow the
outer margin and are narrowly cut with pale opposite the veins. Beneath, yel-
lowish to dark smoky, primaries with a smoky extra median line followed by a
dark shade. Secondaries with a dusky median band and an irregular s. t. shade,
diffuse inwardly, outwardly more or less defined by a yellowish shading. Ex-
pands 1.08-1.16 inches = 27-29 mm.
Hab. — Arizona.
One male and two females from the Graef, Hulst and Neumoegen
collections, respectively- The species resemhles clientis in size and
in the apical blackish spot. It is narrower winged, however, with
less produced apices of primaries, and is much paler, more powdery,
with more diffuse maculation. The marking of the terminal space
is characteristic in the new species, though indications of it may be
made out in clientis.
Bumolocha atomaria n. sp. — Head and thorax dusty gray-brown, im-
maculate. Primaries gray, shaded and powdered with smoky brown, without
contrasting maculation. From the base to the t. p. line the color is rather evenly
smoky brown, except sometimes along costa where it may be gray. T. a. line a
vaguely deeper brown shade, more or less obviously outbent about the middle.
T. p. line a narrow brown band, almost even in course, without teeth or angula-
tions. Beyond this line is the palest part of the wing, shading gradually to the
s. t. line, which consists of a series of small, blackish dots followed by pale scales;
in course it is about parallel with the outer margin. Terminal space paler beyond
the s. t. line, darkening to the ground before the margin, except that the apex is
left pale. There is a narrow, chestnut brown terminal line, and the fringes are
dark. No trace of ordinary spots. Secondaries dusty yellowish gray, the fringes
darker. Beneath powdery ; primaries smoky. Bxpands 1.12-1.20 inches = 28-
30 mm.
AMERICAN LEPIDOPTERA. 217
Hab. — Volga, South Dakota.
Four male examples in good or fair condition, from the late
Judge P. C. Truman. The species is most nearly allied to decepta
lis, but is slighter and very much lighter in color. The palpi are
longer than is usual in the males of this genus, and in that feature
resemble Lomanaltes. But they are straightly projected, and the
wing form is that which is normal in Bomolocha.
Scolecocampa atriluna n. sp. — Ground color of head, thorax and pri-
maries an even, soft, creamy clay yellow. Palpi brown at the sides, else head
and thorax immaculate. Primaries with a round black spot at the base of the
cell; a small, puuctiform dot at the place of the orbicular, and a prominent
lunate reniform at the end of the cell. A small blackish costal spot indicates the
inception of the t. p. line, and a small brownish line on the inner margin sug-
gests its end. There is a series of small terminal blackish dots at the ends of the
veins. Secondaries more yellowish at base, with a broad, smoky outer margin
and a moderate, smoky discal spot. Beneath, more ocher yellow, with an extra
median diffuse powdery blackish band, less obvious on secondaries, and a distinct
blackish discal spot. Expands 1.40 inches = 35 mm.
Hab. — Huachuca Mts., Arizona.
A single female from Dr. Barnes. The species is amply distinct
from the common form by the very even coloring of the primaries,
which lack all powdering, and by the very distinct sharply defined
black reniform. It is quite probable that further material will show
that the t. p. line may become complete.
EUCALYPTR4 Morr.
1875, Morr., Ann. Lye. Nat. Hist. N. Y., xi, 104.
Head moderate in size, closely applied to the head, but hardly
retracted ; front full, hardly protuberant, smooth ; eyes naked, large,
hemispherical, not protuberant ; tongue weak, not functional, of
moderate length or very short; palpi long, oblique, with long scales
on the second joint, directed downward and giving it a compressed
appearance, terminal joint moderate, slightly drooping; forming
with a pointed frontal tuft a snout-like appearance; antenna? in the
% with the joints long, with long lateral bristles and small tufts of
shorter hair, the anterior angles somewhat marked. The thorax is
small, only a little convex ; vestiture scaly, forming no tufts, collar
and patagia marked but not relieved ; legs of moderate length,
rather stout, unarmed, save for the usual spurs. Abdomen long and
stout, reaching to or exceeding the anal angle of the secondaries,

untufted. Primaries moderate or rather large, varying somewhat
in width, costal and inner margin shouldered, then subparallel or
gently curved, apex rectangular, hind angle obtusely rounded ; vena-
tion normal, veins 7, 8 and 9 on one stalk out of the end of the
accessory cell ; 7 branches at less than one quarter the distance to
the margin, 8 and 9 diverge at about one half way between cell
and apex. Secondaries proportionate, vein 5 as strong as the others,
out of the weak cross vein at about one third the width of the cell.
The species are very similar in appearance and type of macula-
tion. The primaries have no transverse maculation, except a punc-
tiform or fasciform t. p. line; there is a tendency to form a longitu-
dinal shading through the middle, usually accompanied by the loss
of the transverse marking ; the ordinary spots are reduced to small
dots and one or both may be entirely wanting. In color the range is
from snowy white through creamy yellow to smoky brown or blackish.
Stygialis is the largest and darkest form, the color being a uniform
smoky blackish on both wings, the maculation a black, diffuse
streak through the centre of the primaries. The species is from
Southern Arizona, and has an unusual admixture of flat hair in the
thoracic vestiture, as well as a better developed tongue than the
other species.
Strigata has the same longitudinal maculation, but is creamy
white in color, with smoky powdering. The tongue is here decidedly
weak, but is longer in the female than it is in the male.
Bipuncta is a broad winged species, almost as large as stygialis,
and the only one in which there is a complete band at the place of
the t. p. line ; this band varies much in distinctness, but seems to be
always present and is often well marked. In color the primaries
range from creamy to smoky gray, the difference being mostly due
to the variable number of smoky atoms powdered over the light
base.
Obscura Grt. belongs here and differs in its somewhat larger size,
much darker color and less obvious t. p. line.
Nivealis has the wing form of the preceding; but the primaries
are white, immaculate, except for a gray dot on the cross vein at
the end of the- cell.
Humeralis is narrower winged, with the shoulder of costa and
inner margin of primaries well marked. The color is creamy yel-
low, powdery, and tends to become brown or smoky at the outer

margin, the fringes being usually darker than the rest of the wing.
The t. p. line is punctiform in this species, usually traceable, and
there may be a fairly obvious longitudinal dusky shading through
the middle of the wing.
Umbonata has the wing form of the preceding, but the primaries
are uniformly smoky brown, and the secondaries are not much
lighter. The discal dots are traceable in most specimens, and in
one example there is an indicated t. p. line; but all maculation may
be completely absent.
Apicalis is similar to humeralis at first sight ; but the primaries
are decidedly more pointed, the color is more even, there is no dark-
ening outwardly and no t. p. line or longitudinal shading on any
specimen.
Minorata is the smallest of the species; like apicalis in wing form
but darker, with an exterior line almost as continuous as that in
bipuncta, ami in the type specimen a very decided indication of a
t. a. line.

Beneath paler, smoky gray, powdery, else entirely immaculate. Expands 1.36
inches = 34 mm.
Hab, — Southern Arizona, Poling.
One male example in good condition, received from Dr. Barnes.
The chief differential characters of this species have been already
mentioned. Its relationship to the others of this genus is obvious,
and in wing form it most nearly resembles bipuncta.
Eucalyptra ni * ealis n. sp. — Front of the head, palpi and anterior legs
rusty brown or paler Head above, thoracic disc, base of abdomen and primaries
white, slightly lustrous, and in some points of view with a slightly yellowish
tinge. Primaries with a very narrow, broken brownish terminal line, which
may be wanting. Discal dots very small or wanting. A faint brownish tinge
along the median vein. Secondaries smoky yellowish, immaculate. Beneath,
primaries smoky; secondaries yellowish, smoky along the costal margin. Ex-
pands 1.08-1.16 inches = 27-29 mm.
Hub.— Hastings, Florida (Barnes) ; Iowa City, Iowa, June 23
(Wickham).
Two good males very similar in appearance, despite the widely
separated localities. The Iowa City example came from the Kemp
collection, and is dated in 1898. The tongue is very weak and
short; the wing form is essestially as in bipuncta, but there is a
more obvious shoulder on the inner margin. The species should be
easily known by the white primaries which are free from powderings.
Eucalyptra humoral is n. sp. — Ground color yellowish, varying in tint
and variably black or brown speckled. Front of the head, palpi and anterior
legs seal brown. Primaries tending to darken outwardly, fringes usually darker
than the rest of the wing. Most of the specimens with a fairly obvious puncti-
form t. p. line, and in some specimens a darker shading below the median vein
indicating a longitudinal shade. A series of brown or blackish terminal lunules.
Discal spots black, punctiform, the orbicular tending to become the larger and
more prominent. Secondaries smoky, with a yellowish tint, fringes tending to
blackish. Beneath, primaries very dark smoky, often with the discal dots of the
upper surface reproduced; secondaries usually paler, except along the costa.
Expands .80 -1.20 inches = 20-30 mm.
Hab. — North Carolina, in August; Hastings, Florida, in April,
June, September and October.
Thirty males and two females are before me, most of them in
good condition. The Hastings specimens come, in part, from Dr.
Barnes, in part from Mr. Kearfott, and in part from Mr. Franck.
This is the most stumpy- winged species of the series; the prima-
ries being broad and short, with a distinct shoulder on the inner
AMERICAN LEPIDOPTERA. 221
margin. It is also rather more deeply yellow in ground color than
the other species, and owes the outward darkening less to a denser
powdering than to a deepening of the actual tint. The tongue is
very weak, and in some examples also very short ; but that seems a
variable quantity.
In one example the longitudinal streaking is sufficiently well
marked to suggest strigata, but the much broader wing, the distinct
t. p. line and the very dark under side serve as distinctive charac-
ters. It seems that, in this species, the stumpiest wings are best
marked, and that all the markings intensify in similar proportion.
Eucalyptra uuiboiiata n. sp. — Head, thorax and primaries a deep
chocolate brown, somewhat lustrous. Primaries with a series of darker terminal
lunules. In some specimens a punctiform t. p. line is indicated. Discal spots
punctiform, black, usually present, and in one example the reuiform is geminate.
Secondaries a paler, more smoky brown, palest at base. Beneath, dull chocolate
brown, powdery, immaculate. Expands 1.00-1.16 inches = 25-29 mm.
Hab. — Hastings, Florida, April (Kearfott) and June (Barnes).
This has the general wing form of humeralis, but is easily distinct
by its uniform chocolate brown color, which is not due to a powder-
ing or an overlay upon a lighter base. The tongue is weak and
only moderate in length. I have eight examples, all of them males.
Eucalyptra apicalis n. sp. — Front of head, palpi and anterior legs
brown. Head above, thorax and primaries whitish, with fine black powderings.
Primaries with a punctiform terminal line and punctiform discal spots, else im-
maculate. Secondaries creamy white or yellowish to smoky gray, immaculate.
Beneath, smoky gray or brownish, more or less powdery. Expands .80-1.00
inches = 20-25 mm.
Hab. — Hastings, Florida, June 8th to 20th (Barnes) ; September
21st to October 6th (Kearfott).
Six $ and four 9 examples, varying only in the apparent color-
ation. The June specimens are as a whole more gray than those
dated September and October, and they are also the larger. Other-
wise there seems no difference, and in none is there any appearance
of a transverse or longitudinal line or shade. The tongue is much
reduced, and in some exemples seems almost wanting at first sight.
The character of the wing form has been already discussed.
Eucalyptra minorata n. sp.— Ground color whitish, so densely pow-
dered with black as to seem gray. Palpi, head beneath and anterior legs brown.
Primaries with a heavier powdering to form an evenly curved very obscure t. a.
line over the punctiform orbicular. T. p. line continuous, single, fasci form, bent

over the cell and rigidly oblique from the angle to the hind margin. A lunuate
terminal line. Discal spots black, punctiform. Secondaries smoky gray, with a
darker terminal line; else immaculate. Beneath, smoky brown, powdery ; sec-
ondaries with a blackish discal lunule. Expands .76 inches = 19 mm.
Hub. — Hastings, Florida, October 4th.
One male specimen in rather poor condition, from Mr. W. D.
Kearfott. This is the smallest species of the genus, and it is unfort
unate that there should be one example only. The traceable t. a.
line of the primaries above and the dusky lunule of the secondaries
below should make the species recognizable. The tongue is moder-
ate in length but weak.
ARETYPA n. gen.
Head rather small, closely applied to the thorax, yet not re-
tracted ; eyes naked, hemispherical, somewhat protuberant; front
full, smooth ; palpi oblique, exceeding the head by more than its
own length, basal joint moderate, rather slender, second joint trans-
versely flattened at tip, vestiture directed forward and downward,
terminal joint a little drooping; antenna of male lengthily bipecti-
nated, the branches ciliated, each branch with a curved bristle at
the inner side of the tip; tongue spiral, moderate in length and
apparently functional. Thorax moderate, subglobose, vestiture com-
posed of flattened hair forming no tufts; collar and patagia not
relieved; legs long and slender, closely scaled, with the usual spurs
long, but otherwise unarmed. Primaries trigonate, proportionately
large, apex a little pointed ; venation normal, veins 7 and 9 from
the end of the accessory cell 8 out of 9 half way to the apex. On
the secondaries vein 5 is weaker than the others, though fairly well
developed, and is from the cross vein about one-third across the cell.
This genus differs from Eucalyptra in the lengthily pectinated
antenna of the male, in the slender, longer legs, and in the differing
form of the primaries which have the outer margin a little excava-
ted below the apex. These points were noted in my description of
the species referred here; but I thought at that time that it might
remain associated with bipuncta ; the occurrence of so many other-
species, all closely allied would leave pectinicornis as an abnormity
and it is therefore separated as the type of the present genus.
Amolita obliqua n.sp. — Head and thorax creamy yellow, with a pinkish
flush, immaculate. Primaries with a more or less obvious reddish flush over a
pale yellowish base, an admixture of brown and blackish scales giving the wings
AMERICAN LEPIDOPTERA. 223
a vague powdery appearance. A dusky brownish shade band extends rigidly
from the inner margin, about two-fifths from base, to the apex. A second, nar-
rower and less obvious but similar band extends from the inner margin two-
thirds from base and curves gently outward to the apex where it meets the. rigid
band. There is a series of black terminal dots and a pale line is at the base of
the fringes. The orbicular is a minute black point. The reniform is indicated
by a somewhat larger dot in some specimens, but may be entirely absent. Sec-
ondaries a pale glistening yellowish white, immaculate. Beneath, somewhat
ocherous, powdered with darker scales; secondaries with a small discal spot.
Expands .80-1.00 inch = 20-25 mm.
Hub. — Hastings, Florida, April, September 20th to October 21st.
A series of 16 males and 2 females from Mr. W. D. Kearfott are
readily distinguished from fessa by the rigid inner shade band, which
runs direct from apex to inner margin and does not curve downward
along the median vein. There is in some specimens a dusky shad-
ing along the median vein or in the cell, but it is indefined and does
not join the definite band. One of the two females is larger than
any of the males, and it is probable that this difference in size will
prove to be the rule.
V in nli I a roseola n. sp. — Head and thorax dull white, with an admixture
of reddish scales that gives a faint rosy tinge, else immaculate. Primaries yel-
lowish white, with a sufficient admixture of red scales to give a very decided
rosy tinge, through which the veins are traceable in the ground color; an admix-
ture of darker scales gives the wing a somewhat powdery appearance. A some-
what indefinite deeper shading runs from base through the cell to the apex, and
another of the same kind from base through the submedian interspace, curving
toward the apex from about the middle of the wing. The orbicular is indicated
by a small black dot, and the reniform by a pair of such dots. There is a pow-
dering of blackish scales in the submedian interspace, which may form a black
mark near base and a short spur near the middle of the space. The terminal
spots are black and linear; really a broken terminal line. Secondaries whitish,
glistening, with a vague wash of yellow and pink. Beneath, red along the costa
only, fading toward the interior. Expands .60-. 80 inches = 17-20 mm.
Hub. — Hastings, Florida, March and October.
Six males, from Mr. Kearfott, vary decidedly in the distinctness
of the maculation on the upper side. In one example there is
scarcely a trace of the shade lines, and only the ordinary spots are
marked; in another both are emphasized by black scales and very
clearly seen ; between these extremes the other specimens range.
The lack of antennal pectinations in this species has been already
referred to as distinctive. I have two female examples in which the
primaries are almost lanceolate, and the secondaries are white. The

maculation is exactly that above described, and did they come from
the same region 1 would consider them as belonging with my male
examples, but they come from Texas, in April, and the differences
are sufficient to leave me in doubt ; therefore, the examples are
merely mentioned as possible females of roseola..

AMERICAN HYMENOPTERA. 22*
Descriptions of New Species of* HYMENOPTERA taken
by Mr. Edward Whyiuper on the "'Higher
Andes of the Equator."
BY P. CAMERON.
(New Mills, by Stockport, England.)
The circumstances under which the Hymenoptera described here-
with were taken are related by Mr. Whymper in his "Travels
amongst the Great Andes of the Equator," 1892, p. 856. The
parasitic species I have described in "The Entomologist" for the
present year.
SCOLIID.E.
t'ainpsomeris (Elis) ephippiuin Say.
The form taken by Mr. Whymper is C. Wagneriana Saussure,
which was described from Chimborazo. It differs from the type in
having the wings clear, or almost clear, hyaline; whereas in the
type they are dark fuscous violaceous. The orange bands on the
abdomen are paler than in the type. The species was taken by Mr.
Whymper at Betiocen, Pinantura and Antisanella, 11,000 feet;
Guallabamba to Guachala, 7500 feet, and Ambato, 8000 feet.
The var. Wagneriana is probably a high-mountain form. It is
figured by Mr. Whymper in his travels, p. 96, and he mentions there
that it is known by the name of "the Bishop."
CampMomeris (Elis) costalis Lep.
One example of this common neotropical species from 8. Lucia,
8000 feet.
Caiiipsomeris (Dielis) argenteopilosa sp. nov.
Black; the head and thorax densely covered with silvery pubescence and with
black hair; the apices of the second and third abdominal segments fringed with
white hair; the wings hyaline, the radial cellules tinged with dark fulvous; the
radial cellule long, projecting largely beyond the cubital. % . Length 20-21 mm
Head punctured, except for a broad curved line on the top of the front and
the clypeus, except round the sides and tojt ; the smooth parts are bare ; the rest
punctured and bearing stiff black hairs; the occiput and outer orbits are thickly
covered with pale hair. Mesonotmn punctured closely, but not strongly; the
apical part in the middle smooth. The scutellum is similarly punctured, except
in the middle which is smooth, the smooth part being broadest at the apex. The

post-scutellum and the median segment are closely and uniformly punctured
throughout, densely covered with silvery pubescence and with black hair. The
hair on the legs is white: the spines and calcaria are black ; the coxae are cov-
ered with silvery pubescence. The radial cellule is long, fully two-thirds of the
length of the second cubital ; the basal abcissa of the 'adius is roundly curved
upwards ; the apical is straighter and has an oblique slope ; the second transverse
cubital nervure is received near the middle of the cellule, it has the upper (and
larger) part straight and oblique; the lower part is also oblique, but more
rounded; the first recurrent nervure has the upper part straight and oblique;
the second has the lower two-thirds broadly rounded backwards; the upper part
straight and oblique. Abdomen deep black, thickly covered with black hair;
the second and third segments are fringed at the apex and laterally with white
hair, the apical half of the pygidium is smooth and bare.
Hab.— Ecuador, 1-2000 feet.
Characteristic of this species is the elongated radial cellule pro-
jecting largely beyond the apex of the cubital.

Pepsis sulci irons sp. nov.
Black; the head and thorax covered thickly with a bright green pile; the
abdomen with a bluish green pile ; the legs dark blue, their base covered with a
green pile; the wings fuscous, their lower basal half and a broader baud extend-
ing from the transverse basal nervure to the third transverse cubital through the

with fulvous in the middle. £• Length 18 mm.
Scape of antennas thickly covered with green pubescence; the flagellum black,
fuscous towards the apex. Head thickly covered with bright green pubescence
and sparsely with long black hair; the front has a wide and deep furrow down
the centre from the ocelli to the base of the antennae. Clypeus transverse at the
apex ; the labrum is large, broadly rounded in front. Mandibles and palpi black ;
the former covered with green pubescence at the base; their apical tooth is long
and bluntly rounded at the apex. Metanotum irregularly transversely striated,
the striae extending on to the upper half of the rnetapleurae ; the apex has a
straight oblique slope. The yellowish cloud in the fore wings occupies the lower
edge of the radial, of the first cubital, the whole of the second and third cubital,
except for fuscous streaks in the centre, the greater part of the discoidals and of
the submedian and anal cellules; in the first discoidal is an elongated fuscous
cloud with a hook-shaped projection at the base. The second cubital cellule is
distinctly longer than the third.
Hub.— Nanegal, 3-4000 feet.
Pepsis andicola sp. nov.

row is deep; the apex of the clypeus is broadly, roundly bilobate ; the middle
being slightly, but distinctly incised. Mandibles and palpi black, opaque; the
former sparsely covered with black hairs. The thorax is thickly covered with
long black hair, which is shorter and sparser on the mesonotum and longer and
denser on the median segment and on the sternum. The scutellum is glabrous.
but this may be through rubbing; the post-scutellurn is also without hair; the
centre is deeply furrowed, the furrow being much widened at the apex, which is
smooth and shining. The black cloud on the base of the fore wings is narrow,
it not reaching to the middle of the space bounded by the base of the wings and
the transverse basal nervure ; the basal abscissa of the radius is almost straight,
not curved, is thickened at the top and has an oblique slope ; the apical abscissa
is broadly rounded in the middle; its lower bend is not much longer than the
upper; the third cubital cellule is above three-fourths of the length of the sec-
ond. The basal part of the median segment is coarsely, irregularly striated ; its

This species is not unlike H. machachiensis, but may be separated
from it by the 3rd cubital cellule being longer compared with the
2nd, it being not much shorter than it, where in machachiensis it is
hardly one-half its length ; by the 3rd transverse cubital nervure
being roundly curved, instead of having its upper half straight and

Agapostemon peruviaiuis sp. nov.
Head and thorax brilliant emerald-green and thickly covered with long whit-
ish-fulvous hair; the abdomen black; the halves of all segments yellow; the
labrum, mandibles and the greater part of the legs yellow; the antennae, black,
brownish beneath ; wings hyaline, the stigma testaceous, the nervures black. % .
Scape of antennae yellow, black above ; the flagellum black, fulvous beneath,
except on the apical two joints. Head emerald green, except the apex of the
clypeus and the labrum, which are yellow, it is closely but not very closely punc-
tured. The clypeus is large, broadly rounded above and with a bundle of stiff
brownish bristles on the top in the centre ; beneath the sides are broadly roundly
produced and clearly separated from the labrum which has its apex broadly
rounded ; its sides are rounded and it is clearly separated above and covered with
short white pubescence. Mandibles thickly covered with golden pubescence,
yellow, their apex piceous. Thorax brilliant emerald-green, closely and distinctly
punctured. The mesonotum is more closely punctured than the rest; it bears a
central and a lateral golden impressed line; the scutellum is more distinctly and
less closely punctured ; the area on the median segment is large, rather strongly
reticulated; the apical slope is clearly limited and bears some irregular, curved
stria;. Pleurae closely and strongly punctured, the punctures running into stria-
tions; the hinder part of the niesopleurae is irregularly striated, and at the base
is bounded by a curved furrow; the lower part of the metapleurae bears some
irregular striae, which are longest on the apex. The four front legs have the
coxae and trochanters black ; the latter streaked with yellow in the middle; the
hinder coxae are emerald-green and closely striated above; the rest brownish;
the hind femora black, with abroad yellow line on the apical half above; the
hinder tibiae are dark brown, yellow beneath. The yellow band on the 1st ab-
dominal segment is on the apex, on the others on the basal half, the apical two
bands are narrower than the others; the ventral segments have similar, but nar-
rower bands.

Antennae black, the scape dark brown. Head smooth and shining ; the cly-
peus, lower inner orbits and the labrum yellow ; the clypeus with a few scattered
punctures; a smooth, black shining keel leads down from the front ocellus. Man-
dibles brownish-black, brighter, more rufous in color in the middle. Thorax
thickly covered with long fulvous hair, except on the centre of the median seg-
ment, which is bare, smooth and shining and dark brown in color. The hair on
the coxse, trochanters, femora and anterior tibire is long, dense and pale fulvous
in color ; on the 4th anterior tarsi it is rufous, except on the middle tibia? and base
of tarsi iu front, on which it is black ; on the hinder tibise and tarsi it is for the
most part black. The 2nd cubital cellule is small, at the bottom about one-fourth
of the length of the 3rd ; at the top it is narrowed, the transverse cubital nervures
(which are roundly curved) almost touching there. The five, apical dorsal seg-
ments have a distinct metallic tint and are shining; the last ventral segment is
broadly raised in the middle. The hinder tibise are slightly curved; the outer
spur of the hinder calcaria is long, curved, broad at the base, becoming gradually
narrowed towards the apex and finely pectinated in the middle ; the inner is
longer, narrower at the base and much more stoutly combed throughout; the
2nd and 3rd tarsal joints of the posterior legs are dilated and compressed beneath ;
they become gradually, roundly wider from the base to the apex ; the labrum is
roundly convex and unfurrowed.

Some Notes ou the Bee Genus ANDREW A.
BY LAWRENCE BRUNER.
Several years ago the writer undertook to determine and lable
the bees contained in the collection of insects belonging to the Uni-
versity of Nebraska. After some preliminary work in the way of
assorting and arranging the material at hand, and securing litera
ture with which to do the naming, it was found that the large num-
ber of the species belonging to the genus Andrena in its broad sense
could only be placed by the aid of some kind of synoptic key or
table. Not being able to find such an aid in our entomological
literature it was decided to construct one for the purpose.
This being decided upon, it was soon ascertained that the various
authors who had established the already recognized and recorded
species had used different characters upon which to base their de-
scriptions. The use or choice of distinct characters by the various
authors when describing their species made it very difficult for the
writer when attempting to decide upon the principal features of the
proposed table in order to make it as nearly a natural one as possi-
ble. After several vain attempts at employing structural characters
for the separation of the main groups, at least, all efforts in this
direction ceased, and such secondary characters as the presence or
absence, length, abundance, color and arrangement of pubescence
were employed instead. This choice was made necessary because,
as stated above, the various authors when characterizing their new
species had overlooked many of the structural characters now used
in the limitation of forms.
While nothing like perfection is claimed for the present table as
it now stands, it has been a great help to the writer in his attempts
at placing the hundred or more forms belonging to the collection
which he is working over. It is with this knowledge in mind that
the table is offered to others who may be interested in our Andrenid
bees. Later, after more of our species that are still undescribed
have been determined and characterized, and when both sexes of
some known species have been recognized, a new and better table
can be constructed.

In describing bees of this group it would be well to employ such
characters as punctuation of face, thorax and abdomen ; the nature
of the triangle (inclosure) at the base of the metathorax — whether
bounded by a rim or by an impressed line; its surface, whether
rough or smooth ; shape and size of head and its attachments, as
antennae, tubercle at apex of clypeus, mandibles, etc. ; form of abdo-
men, depression of apical portion of segments; any special charac-
teristic of legs, as of tibiae and tarsi ; pubescence, length, abundance,
arrangement, color, etc. ; general color of wings, and indication of
variation of form and size in cells, nervures and stigma; abundance
and color of anal fimbria in the female ; also the general color of
the insect or of any portion of it. If all, or most, of these points
are kept in mind when a new form is characterized, the difficulty of
its recognition by others will be greatly lessened. It will also
enable the would-be tabulator to construct his key on characters
that are less artificial and therefore more constant than those em-
ployed here.
While working over the described American forms it was found
that a few synonyms occur. In order to make the paper a trifle
more complete there are added below :

The following normally three-celled species are also occasionally
found in which one or both wings have but two submarginal cells:
bipunctata, claytonice, hippotes, platyparia, robertsonii, soliduginis,
personata, asteris, krigiana, milwaukeensis, etc.
Since this table was finished, Dr. S. Graenicher, of Milwaukee,
Wisconsin, has published a paper in the Canadian Entomologist
June, 1903, pp. 162-166), in which five additional species are
described. As a remodelling of the table at this time is impracti-
cable, it may suffice to indicate briefly where these new forms would
fall:
The species thaspii Graen., 9 , will come in the vicinity of frigida
Sm., or lauracea Rob., both of which it resembles in some respects.
Cockerelli Graen., 9 , comes nearest macoupinensis Rob., from which
it differs by having the facial fovere black instead of pale, and the
fimbria purplish instead of ochraceous. The male of Cockerelli
may be compared with perarmata $ , but lacks the tooth at base of
mandibles of the latter. Milwaukeensis Graen, 9 , is nearest to
impuncta Kby., but differs from it by having the pubescence on two
basal segments of abdomen ochraceous to fulvous, instead of whit-
ish. The male of this species has the pubescence entirely fulvous,
and the head extremely broad. The viburnella Graen., 9 , will fall
in the vicinity of rufosignata Ckll., and his albofoveata 9 seems to
come near platyparia Rob., and hartfordensis Ckll.

STUDIES IN AMERICAN BEATTID.E.
BY JAMES A. U. REHN.
Of the Academy of Natural Sciences of Philadelphia.
The following notes are the results of an examination of all the
undetermined American Blattidre in the collection of the Academy
of Natural Sciences of Philadelphia, and a large amount of material
from the United States National Museum. The latter consisted
chiefly of the Schild and Burgdorf collection from Costa Rica, and
the Palmer and Riley collection from Cuba.
The collections of the two institutions are indicated in the follow-
ing pages by their respective initials.
The author is indebted to Mr. W. H. Ashmead of the U. S.
National Museum for the privilege of studying the material belong-
ing to that institution.

expanded into lateral plates which extend over and embrace the bases of the
cerci, the central portion extended and apically rotundate. Subgenital plate
broad, spoon-shaped, the apex moderately emarginate. Cerci rather long,
depressed, acuminate. Anterior femora equalling the coxae in length, inferior
margin in the apical half closely set with spines; tibiae with the spines on the

this specimen exhibits what appears to be a singular color pattern,
which might warrant description.
General color sienna. Head with the eyes and the interspace between the
same wood brown; ventral aspect of head dull yellowish; antennae with the
first and second joints yellowish, the remainder black, the two colors gradually
merging. Pronotum pale yellowish, marked with two large longitudinal
blotches of blackish brown which flank the median bar of the basic color, these
being reinforced laterally by a single narrow line of the same tint; lateral lobes
pellucid. Tegmina with the basal field, the interspace between the ulnar vein
and anal sulcus, and a median space in the anal field pellucid ; anterior portion
of the marginal field much lighter than the general color and subpellucid.
Wings with the costal region infuscate.

1811, Blatta angustata Latreille, in Humboldt and Bonpland, Rec. d'Observat.

Six specimens ; three males, three females; San Carlos, Costa
Rica. (Schild and Burgdorf.) [U. S. N. M.]
This series is very interesting, and justifies Saussure's association
of venosa with this species as a synonym.* In the Biologiaf
Saussure and Zehutner tentatively admitted venosa as a species,
stating that the differential points were that venosa has the ulnar
vein of the wing with two branches, and the apical margin of
the wing is not or only very slightly infuscate, while in angus
lata " the wings are infuscated on the apical margin and have
three ulnar branches." The specimens examined have the ulnar
vein with two or three branches, and the apical margin is very
slightly or very strongly infuscate.
Pseudophyllodromia pavonacea n. sp.
Type : % ; Bartica, British Guiana. May 21, 1901. (R. J.

This species in general form resembles P. angustata (Latreille),
but the venation of the tegmina and coloration ot the disk of the
pronotum are quite different, the lormer resembling P. fasciatella
and the latter is similar to P. peruana. Relationship also exists
with P. obscura Saussure from Brazil, and P. semivitrea Brunner
from St. Vincent. From the former it differs in the unmarked
pronotum, and from the latter in the more elongate tegmina, the
different markings on the pronotum, and the greater interspace
between the eyes. No affinity exists with P. histrio Saussure or
* Miss. Scient. Mexiq., Orth., p. 44.
fBiol. Cent.-Amer., Orth., i, p. 47.
AMERICAN ORTHOPTKRA. 263
P. heydeniana (Saussure), and the closest relationship is undoubt-
edly with obscura. The species described from Grenada, P. albi-
nervis Brunner, considerably resembles pavonacea, but can be imrae
diately distinguished by the much smaller size.
Size rather large. Head with the interspace between the eyes about half the
short diameter of the eye, the interspace between the bases of the antennae equal
to the eye dimension ; eyes ovate ; antenna* filiform, considerably exceeding the
body in length. Pronotum transverse; anterior and posterior margins slightly
produced centrally; lateral margins broadly rounded. Tegmina moderately
elongate, subequal in width, the apex narrowly rounded ; basal field narrow,
acuminate; costal uervures fourteen in number; discoidal vein with two apical
forks; median vein and its accessory rami parallel with the discoidal ; anal field
elongate sub-pyriform, containing five uervures, anal sulcus straight for a consid-
erable part of the distal section. Wings rather narrow; costal uervures eleven in
number; axillary vein with three additional branches. Subgeuital plate acumi-
nate. Cerci short, stout, depressed, and acuminate, supplied with long hairs.
Anterior tibia? considerably shorter than the femora, spines in two rows; meta.
tarsi exceeding the remaining tarsal joints in length. Median tibia? equalling the
femora, spines in three rows ; metatarsi half as long again as the remaining tarsal
joints. Posterior tibia? considerably exceeding the femora in length, spines in
three rows ; metatarsi over twice as long as the remaining articles.
General color wood brown on a base of pale amber color. Head with antenna?
plain wood brown. Pronotum pellucid ; marked with a median outlined lyrate
pattern of black, which carries an additional fine curved black line on the
anterior external section, connecting the middle of either arm of the central pat-
tern with its anterior extremity. Tegmina wood brown, the costal, discoidal
and anal field finely lined with pellucid ; a large rounded spot at the base of the
discoidal field is similar in character; basal field pellucid. Wings pellucid, the
edge of the costal region suffused with smoky brown. Upper surface of the
abdomen reddish brown. Ventral surface including limbs pale brownish, the
vicinity of the bases of the spines on the limbs darker brown.

Type. — By elimination and selection, Blatta germanica Linnaeus.*
It will be seen that the species remaining in the genus are ger-
manica, bivittata, supelleetilium and alternant*. Of these germanica
can very rationally be selected as the type.
The name Phyllodromica Fieber (Lotos, iii, pp. 93-94, 1853),
proposed independently, and not as an emendation of Phyllodromia,
has been generally disregarded. The species he placed in the genus
after examination are as follows :
pallida Oliv., . . Aphlebia Brunner, 1865.
perspicillaris Herhst., Ectobius Stephens. 1835.
punctulata Fieb., . (Congeneric with perspicillaris.)

sardea Serv., . . Aphlebia, 1865.
Megerlei Fieh., . . "
marginata Fabr., . "
macidata Charp.,
decipiens Germ.,
limbata Charp., .
As seen above, Aphlebia must give way to Phyllodromica Fieber,
and of the included species, punctata {= Megerlei) can well be
selected as the type, as Brunner figured this form.

Allied to P. brunneriana (Saussure), but differing in the larger
size, the greater interspace between the eyes (two-thirds instead of
about one half of the interspace between the antennal bases), the
presence of cross nervures in the anal field of the tegmina, the
greater number of branches (five instead of three) to the median
vein of the same, and the slenderer limbs.
Size rather large; form elongate ovate; surface polished. Head with the
interspace between the eyes about two-thirds that between the antennal bases;
eyes acuminate pyriform, somewhat prominent: antennae exceeding the body
by about one-half the length of the latter. Pronotum transverse, subovate :
anterior and posterior margins truncate, laterals rounded, the postero-lateral
angles being obtuse; disk with a transverse shallow depression before the mid-
dle; lateral portions hardly deflected. Tegmina elongate, subequal, apex sub-
acuminate ; basal field occupying about one-third the total length ; median vein
with five distinct rami ; anal field pyriform, the five uervures contained therein
connected by cross-nervu res, spurious longitudinal nervures also present between
some of the larger nervures. Wings with the costal veins clavate ; ulnar vein
with five rami. Supra-anal plate sub-triangular, apex entire. Subgenita) plate
produced, the apex consisting of a rounded tubercle, flanked by a deep but nar-
row emargination, the lateral margin terminating at this sinus in the form of a
blunt tubercle, the appearance of the whole apex being rather tridentate. Cerci
moderately long, acuminate, depressed. Anterior femora bearing three median
and one apical large spine and a row of small proximal spines on the anterior,
and four spines on the posterior margin. Median femora bearing six spines on
the anterior, and four on the posterior margins. Posterior femora with four
spines on each margin. Posterior metatarsi over half again as long as the
remaining joints combined.
General color ochraceous brown. Eyes rich wood brown ; disk of the pronotum
reddish ochraceous, the lateral portions and anterior margin pellucid. Upper
surface of the abdomen pale blackish-brown, the margins of each segment paler.

The form here described is very distinct from the latter.
% . Form medium build, elongate ovate; surface polished. Head with the
interspace between the eyes less than that between the ocelli; antenna moni-
form, not of great length. Pronotum transverse subovate, the anterior and pos-
terior margins truncate, the laterals with a very broadly rounded angle; lateral
portions somewhat depressed. Tegmina elongate, about equalling the wings in
length ; basal field not exceeding one-third of the tegmina in length, and the
greatest width does not exceed one-fifth the total length of the same field ; costal
nervures numerous, oblique, parallel, becoming interlaced and ramose toward
the apex of the tegmina; discoidal field with the veins generally longitudinal in
disposition; anal field elongate pyriform, tbe apex rounded, the anal sulcus
meeting the margin of the tegmina at a right angle, veins little curved, sub-
parallel. Wings with tbe apex narrowly rounded, the anterior field being sepa-
rated by a comparatively deep emargination ; costal region considerably eruargi-
nate basally, the costal nervures about ten in number and very slightly enlarged

ing in the much smaller size and very different coloration. The
species described by Walker* as E. arctata appears to belong to the
same group, but has the antennae as long as the body as well as of a
black color. The description is so imperfect that little can be done
with it.

Type: ?; Bartica, British Guiana. May 9 1901. (R. J. Crew.)
[A. N. S. Phila.]
Apparently allied to E. crassa Saussure from Mexico, and E. brevis
Brunner* from St. Vincent; differing from the former in the smaller
size, comparatively longer pronotum, the sub-acuminate apex of the

General color reddish brown, sprinkled with spots of dark umber; pronotum
rather uniformly dotted with the deeper color ; tegmina w'ith the blotches evenly
distributed, the basal section of the principal veins rather strongly marked.

Allied to C. carinulata Saussure* from Central America, but
differing in the much larger size, the subtruncate posterior margin
of the pronotum, the different shape of the tegmina, and in the
presence of three spines on the posterior margin of the anterior

Three topotypes, all females, have also been examined. One speci-
men is immature, and has the tegmina and wings undeveloped, but
otherwise is much like the type. The coloration varies considerably
in the series, but is mainly in the intensity. One specimen is very
light and has the characteristic lyrate Epilamproid pattern on the
pronotum distinctly visible, while in the type this is hardly dis-
cernible.
I have dedicated this species to my friend, Mr. Hamilton, who
collected the specimens examined, while attempting the ascent of
Torquino.

Allied to C. gracilis Brunner* from Australia, but differing in
the completely hidden head, the punctate front, the broader supra
anal plate, the slightly emarginate subgenital plate, the longer meta-
tarsi of the posterior limbs, and in the larger pronotum. Some rela-
tionship appears to exist with C. aptera Schulthessf from Northeast

The above synonym appears perfectly correct after an examina-

One of these specimens is more advanced than the others, being
about in the same condition as the specimens described by Saussure.
The other two have the black markings of the upper surface broken
and confined to two longitudinal series of blotches on the pronotum,
mesonotum, metanotum and tegmina, while the abdominal segments
are transversely barred with black.
While quite a few nominal species of Eurycotis are known from
Cuba, it is quite probable that a large amount of material would
show several at least to represent immature stages of other forms.

Three specimens; one male, two females; Turrialba, Costa Rica.
(Schild and Burgdorf.) [U. S. N. M.]
As the female of this species has never been diagnosed, I have
appended a description of the same.
Size small ; form elongate ovate. Head projecting somewhat beyond the pro-
notum ; interspace between the eyes greater than that between the ocelli ; eyes
reniform ; antennae reaching to the apex of the tegmina. Pronotum sub-ovate,
transverse; anterior and posterior margins rotundate-truncate, lateral margins
rounded, the greatest width being posterior; dorsum flat, lateral portions very
slightly depressed. Tegmina sub-hastate, apex acute; basal field reaching to the
middle of the tegmen, sub-scabrous; discoidal vein practically straight from near
the base to the apex, median vein parallel for a greater part the length of the
tegmina, median rami comparatively few in number and rather obscure; anal

AMERICAN HYMENOPTERA. 291
XOTES OX XORTH AMERICA* MlTILLID.t, WITH
DESCRIPTIONS OF XEW SPECIES.
BY AXEL LEONARD MELANDER.
The following notes and descriptions are the result of a study of
several collections of North American Mutillidae. -The paper grew
from a review of the local forms of Central Texas to its present pro-
portions as the study of the various collections revealed interesting
notes. A full list of the species is given in order to supply data lor
distribution, as in many cases the species were taken from unre-
corded localities. Whenever the species was taken in a new State
a * has been prefixed to its Dame. In order to corroborate the
identity of the species the larger part of the material has been
compared with the excellent type-collection of the American Ento
mological Society at the Philadelphia Academy of Natural Sciences.
By this means the variable species have been assigned their places,
and the element of doubt in identifying from descriptions alone the
species of so large and difficult a group has been eliminated. Inas
much as the recent paper by Mr. Win. J. Fox in these Transactions
for l>i99 gives the be<t arrangement of our specie- that paper will
be followed, the species listed in the same order, and the notes given
may be regarded as supplementary to his revision. Nevertheless,
the present writer does not agree in all cases with his scheme of
phyletic relationship; e. g., the association of harmonia with waco,
and the divisions anthophora and imperialis are not based on
phyletic reasoning, and hence are artificial categories; but in the
main the paper is carefully prepared and is of great service to the
student. The great variability of certain of the species, and the
confusing resemblance of others distantly related have combined to
make species definition a hard task, necessitating more lengthy
descriptions than Air. Fox is accustomed to give. Especially in
the Photopsis group is this to be marked. The abandonment of
IJl(ufi)j>-<i-< by Fox and Dalla Torre is as much an extreme as the
erection by others of genera on single characters of certain of these
pale-colored and night flying species. It may be remarked that
individuals of at least one species, danaus, are assignable, some to
Photopsis, others to Odontophotopsis.

Until some experience is gained, the assignment of species to the
various groups given by Mr. Fox will often be confusing. Owing
to the strenuous way in which the females use their mandibles, the
teeth are frequently worn down or quite wanting in old specimens.
In these cases care should be noted before a final decision is given
that the specimen is a new species in an incongruous group. The
differences given on page 221 of Mr. Fox's paper for separating the
groups imperialis and anthophorce are inversely stated, and should
read thus :
First abdominal segment ( 9 ) smaller than second, more or less nodose ; in % the
first and second segments are not similarly sculptured, the first coarser
than the second Gr. imperialis.
First and second segments ( 9 ) sessile; first segment % not more coarsely sculp-
tured than second Gr. anthophorx.
Pygidial structure is sometimes variable within a species, and
hence, although generally a good character, cannot be regarded as
infallible. In similima, for example, the striae are not uniform,
tending to diverge at the tip. Hippoclamia seems to represent the
extreme where the stria? have become transverse, and since as yet no
intermediate gradations have been discovered, this form can be
given specific rank. The structure .of the petiole of the abdomen,
the vestiture and sculpture of the body, in fact every single charac-
ter that can be chosen is subject to greater or less variation. An
interesting character which appears to have been unnoticed hereto-
fore is the peculiar plumose structure of the hairs covering the body
of certain of the Photopsis males. This is often especially notice
able on the abdominal fringes, and recalls the vestiture of the Bees.
In conclusion, I wish to thank the following individuals and insti-
tutions who have generously loaned their collections for unlimited
study: Rev. G. Birkman, of Fedor, Texas; Mr. Samuel Henshaw,
for the Museum of Comparative Zoology, Cambridge, Mass. ; Mr.
Theo. D. A. Cockerell, for unworked material of his own and
belonging to the New Mexico Agricultural College, Mesilla ; Mr.
C. F. Baker, for the Chicago Academy of Sciences; Dr. O. S.
Westcott, <>f Chicago; and my collaborator, Mr. C. T. Brues, of
New York. The types of most of the new species are located in
the collections of these gentlemen as indicated at the end of each
description.
AMERICAN HYMENOPTERA. 293
MUTILLINJE.
Genus 9ILTILLA Linnaeus.
Group grandiceps.
1. Mutilla gramlicep* Blake (1).*
The male and female of this species were found running over a
sandy and pebbly slope at Austin, Texas. The ground was occu-
pied by a colony of ETalietus pruinosus Robertson, which would sug-
gest that this species is possibly parasitic on the bee.
Several specimens, Austin and Fedor, Texas. The upper side of
the abdomen varies in color from reddish to black. This species
resembles quite closely the ant Pogonomyrmez both in color and
movements, and not Attn, as Mr. Fox states.
Group canadensis.
2. Mutilla nephele Fox (3).
Several females from Fedor, Texas, October (Birkman).
3. ^1 nl ilia canadensis Blake (4).
This is apparently the commonest species of Mutilla on this con-
tinent, as the collection contains more specimens of this than of any
other form. We have examined over one hundred specimens from
Massachusetts (July-September), Virginia, and Central Texas
(April-June). The occurrence of this species with the same bee
with which grandiceps associates has been noted in the "Biological
Bulletin," June 1903, p. 4.
Specimens from the south are somewhat smaller and of a purer
yellow than those from the east. Examples of an almost piceous
color are not rare in the Massachusetts series.
4. Mutilla scwvolella Ckll. and Casad. (5).
One female, Luna, New Mexico (Cockerell).
5. M ul ills* conl iniia \ Cresson (7).
A single specimen of this ornate species was secured at Austin,
Texas, April 28, 1901. This individual differs from the Coloradan
type in that the longer hairs of the metathorax, petiole and legs are
glistening white instead of ochraceous. The ground color of the
second segment is dark rufous, overlaid with black pubescence, while
the pubescence of the J |_-shaPed mark is whitish.
* The parenthetical numbers following tne species refer to Mr. Fox's arrange-
ment.

One female, Fedor, Texas (Birkman).
Group simillima.
8. Vlni jlla hi on I i\ aga Cresson (15).
Plate IV, fig. 2 ; petiole of brazoria.
Occurring at Austin and Fedor, Texas, in the variations monti-
vaga to brazoria. April to October.
9. >l ill ilia liippodamia Fox (16).
Plate IV, tig. 42; pygidium.
One specimen, in a lot of simillima collected by the Rev. G.
Birkman at Fedor, Texas, apparently belongs to this species.
While otherwise closely resembling the variable simillima, it is aber
rant in the widely diverging striae of the pygidium and in the
rounded sides of the metathorax.
Of the type specimens of this species one has the antennae red
instead of blackish. The pygidium is transversely rugose, and not
longitudinally so, as stated in the key (see fig. 42).
10. Mutilla simillima Smith (17).
Plate IV, fig.l; petiole.
Mass., Penna., Va., Ky., 111., Tex. (M. C. Z., etc.).
The specimens in the Philadelphia Academy of Natural Sciences
determined as this species have no black on the venter nor on the
second dorsal segment. No hairs arise from the punctures of the
abdomen. Specimens from Texas (Fedor, Birkman) are more or
less black caudally and ventrally and have very sparse erect abdomi-
nal hairs. The species metis, liippodamia, and simillima can be
quickly separated by the sculpture of the pygidium. In metis the
striae diverge widely, in typical simillima they are closely placed
and more strictly longitudinal, the only divergence being at the
very tip of the median ones ; in hippodamia the striae are rugose,
straight and transverse. The Massachusetts specimens are consid-
erably smaller as a lot and have the lighter spots of the second
abdominal segment round. They are variable in the definiteness
of the pygidial sculpture, the striae of which sometimes are quite

faint. In the Texas specimens the lighter markings of the second
segment are larger and quadrate.
One individual from Austin, Texas, exhibits but a single tooth at
the middle of the mandibles; and this in view of its similar habitus,
would lead one to search for it among the species of the group
anthophorce. The lengthened pedicle and first flagellar joints, the
carinse of the lower occiput, the crenulate sides to the metathorax,
the strigose metapleurse, and the sharp, uniform ventral keel, how-
ever, are all characters distinctive enough of simillima to show the
relationship of the Austin specimen to that species.
11. Mill ilia propinqua Cress. (19).
Nebraska, Texas (M. C. Z.), Mesilla Valley, New Mexico
(Cockerell).
12. nutilla oceola Blake (20).
Several males were taken at Wood's Hole, Mass., during August
of last summer, by Mr. Brues. They may possibly be the male of
harmonia Fox, but they seem to belong to this species. The punc-
tuation of the second abdominal segment is uniform and rather
close, the size of the insect is larger and the wings appear to be
shorter than in oceola.
13. Mill ilia Sanbornii Blake (21).
The Museum of Comparative Zoology at Cambridge contains a
specimen of this species without locality label.
Group waco.
14. n ill ilia waco Blake (25).
Plate IV, fig. 3; petiole.
Not rare. Austin and Fedor, Texas.
15. yi ill ilia harmonia Fox (26).
Plate IV, fig. 4 ; petiole.
This species closely resembles M. cypris in color. It measures
twelve mm. in length. Several specimens were taken at Woods
Hole, Mass., during different seasons. Not rare on the sand dunes
at Porter, Indiana. The species is not related to waco.

Plate IV, fig. 12; petiole of medea.
Two specimens of the variety medea Cress, were taken at Fedor,
Texas, May (Birkmau), one with the cephalic hairs black, the other
bright orange above.
Arizona (Westcott) ; Las Cruces, Las Vegas, Mesilla Lark, While
Mountains (6300 feet), New Mexico (Cockered).
One of Mr. Cockerell's specimens was found in combat with
Microbembex monodonta. In view of the similar struggles between
the bee Halietus and Mutilla canadensis, which we have observed,
it may be surmised that this species (var. medea) is a parasite of the
Bembecid.
25. M ul ilia iegina Cresson (39).
Plate IV, fig. 13; petiole.
Rather common, ranging in size from nine to eighteen mm.
Fedor, Austin, Columbus, Texas. (May to September.) New
Mexico (M. C Z.).
26. Mutilla qiiadi'iguttata Say (42).
Plate IV, tig. 14 ; petiole of elect ra.
Not rare, occurring as the typical -form and the variety electra
Blake, at Fedor, Austin and Cuero, Texas. (May to October.)
Although inconstant as to color, this species has produced no
variety as aberrant as a specimen from Fedor. In this individual
the thorax is over one half longer than usual, not constricted above
the middle legs nor rounded posteriorly, but is broadly ovate, with
the sides subparallel. Otherwise the sculpture and color agree per-
fectly with typical quadriguttata.

It is quite doubtful if castor Blake, macra Cresson, and agenor
Fox are valid species. If they are not forms of ferrugata the struc-

ture of the petiole of the abdomen is not a character of sufficient
importance upon which to base their separation. Even in the col
lection of the American Entomological Society the species are much
confused.
28. Mutilla vesta Cresson (44).
Another common species. Woods Hole, Mass., and Austin and
Fedor, Texas. April to October.
The color of the erect hairs of the head and of the strongly spined
legs varies from red to black. Most of the Eastern specimens differ
from the typical vesta, although the typical form is found with them
also. The following variations seem to be fairly constant, and may
be tabulated :
Vesta. — Striae of pygidium suddenly interrupted apically, the tip
smooth and subshining ; ventral keel of the first abdominal segment
twice toothed, as represented by the figure, and gradually sloping
off in front. Texas, Massachusetts. (Fig. 16.)
Var. a. — Striae of pygidium more or less interrupted, the apical
portion opaque and granular; ventral keel of same type, but not
angular. Massachusetts.
Var. b. — Striae of pygidium entire ; carina of first ventral segment
strong, truncate anteriorly, as in figure 17. Massachusetts.
These three variations can be distinguished from the next variety
by the rounded spots of the second dorsal segment, the structure of
the petiole, and the finer irregular striae of the pygidium, which
number about fourteen and are confused with numerous shorter
striae.
Var. c. — Striae of pygidium straight, entire, deep and coarse,
numbering not over twelve, without short striae in the interspaces;
ventral keel shaped as in the figure. The lighter spots of the second
dorsal segment are confluent. Five specimens, Woods Hole, Mass.
Because of its close similarity to the other forms of this exceedingly
variable species in form, sculpture and color, it is thought best not
to give this insect specific rank. (Fig. 18 ; petiole.)
29. * Mutilla canella Blake (46 and 75).

M. infensa Mel. and Br., Biol. Bull., 1903, June, p. 24.
Plate IV, fig. 20; petiole.
Head transverse, broadly concave behind, finely and closely punc-
tate, mandibles short, edentate; thorax elongate, sub truncate in
front, narrowed behind, rugoso reticulate, the ridges of the meshes
of the metathorax not raised except where they meet, scutellar scale
prominent; abdomen nearly impunctate, pygidium nearly smooth ;
legs strongly spined. Ferruginous, legs and apex of the abdomen
black, second dorsal with two ovate paler spots, pubescence short,
sparse, stiff, dense and black on thorax and base and apex of second
segment, elsewhere pale yellow.
Woods Hole, Mass. Found running about on the nests of
Htdietus.
This species differs from canella Blake by the broader head, peti-
olate abdomen and smooth pygidium. From cariniceps Fox it is
distinct by its partially black pubescence, impunctate second dorsal,
and by the pygidial structure.
32. 9Iu( ilia texana Blake (52).

Austin and Waco, Texas, September and October.
33. Mutilla clilamydata sp. nov.
Female. Head, thorax, and basal half of the abdomen rufo-piceous, apical half
of abdomen and legs piceous black; rugoso-punctate; largely clothed with ap-
pressed golden-red pubescence and with stubby erect hairs. Head confluentlv
rugosely punctured, not produced behind the eyes, but rather truncate posteri-
orly, cheeks with deep, rather distinct punctures which bear comparatively short
hairs, clypeus truncate, fringed with brown setae; scape thick, bent on outer
third, provided with deep coarse punctures, its yellow hairs sparse, first flagellar
joint but little longer than the second ; mandibles short, triangular, blackened :
palpi piceous; front and vertex with dense, appressed, golden-red pubescence,
and with short, erect, concolorous hairs. Thorax egg-shaped, almost rectangu-
larly rounded to the posterior face of the metathorax, closely and coarsely punc-
tured on the sides, the sculpture above concealed by the dense mat of appressed
golden-red pubescence, among which arise the sparse, stubby, golden hairs, the
hind face of the metathorax less coarsely punctured ; pleura?, coxte and femora

with straggling, whitish, longer hairs. Disc of the first segment of the abdomen
impunctate dorsally, margined however by setigerous punctures; ventrally the
first segment has close, deep punctures, anterior half of the keel obliquely promi-
nent, deeply excised at its middle; seen from above, the petiole is trapezoidal,
the anterior angles but little produced, subacute, posteriorly subsessile with the
second segment; from the side this incisure is not pronounced; second abdomi-
nal segment with subcontinent punctures, its anterior and posterior margins and
a median vague line piceous, anteriorly with appressed black pubescence and
long, stiff, black hairs, the posterior margin likewise clothed, but the erect hairs
are brown and short, elsewhere covered with appressed pubescence and short,
stubby hairs concolorous with the vestiture of the thorax but less dense; ground
color of remaining segments blackish, the pubescence of the third dorsal black,
of the others whitish ; the suberect hairs of the venter, tibia? and tarsi whitish ;
pygidium formed as in texana, with reflexed margin, truncate tip, and longitudi-
nally striate disc, the stria;, however, deep and entire, reaching the entire length
of the pygidium.
Length, 9 mm.
Plate IV, fig. 21 ; petiole.
Several specimens, central Illinois, collected near the town of
Bath, on the Illinois River, August, 1899.
While this species would lead to the group (species 42-50)
defined by Mr. Fox as having the second segment of the abdomen
subsessile with the petiole, and the head comparatively small, vet
its general habitus is much more suggestive of texana Blake.
However, it is quite distinct from that species in the structure of
the keel of the first ventral segment, the longer strise of the pygidium,
the shorter third joint to the antennae, and the denser pubescence of
different color. In texana, the carina ends posteriorly in a distinct
tubercle, while the anterior blade is entire ; the striae of the pygidium
are weak and abbreviated ; and the first flagellar joint is one half
again longer than the second, while the metathorax is less abruptly
declivous.

The Rev. Mr. Birkman has fortunately been able to associate
these two species as sexes of the one form. Both males and females

Lake, Wyoming. The Museum of Comparative Zoology has both
the female and the male from Massachusetts.
AMERICAN HYMENOPTERA. 301
35. iVIutilla precilonota sp. nov.
Female. Ferruginous. Head subquadrate, but slightly wider than the thorax,
the hind angles rounded, the sculpture of the upper surface concealed beneath
the dense covering of golden-yellow matted hairs, the erect hairs of the head
and thorax short and sparse, yellow, punctures of cheeks strong, clypeal margin
lightly crenulate ; antennae pale ferruginous, scape more slender but sculptured
and clothed as in obscura, i. e., with uniform, sparse, short hairs and rather coarse
punctures; mandibles slender, acute, uniformly bent, black apically, palpi rufo-
piceous. Thorax broad and truncate in front, due to the expanded dentate
humeri, sides of mesothorax parallel, metathorax narrowed, truncate posteriorly ;
seen from the side, the dorsum presents a convex outline, dorsum coarsely punc-
tured, becoming reticulate posterior to the metathoracic spiracles, the disc of the
metathorax, however, smooth and impunc.tate, sculpture above largely concealed
beneath the matted golden-yellow pubescence, pleurae impunctate except above
the middle coxse. Disc of petiole of abdomen smooth, margins with deep punc-
tures, petiole nodose, strongly constricted from the second segment, apically with
a patch of silvery pubescence, its anteriorfangles dentiform, the ventral keel not
deep, convex, entire; disc of second segment with deep subconfiuent punctures,
those of the under surface more separated and rounded, remaining segments with
smaller and denser punctures ; the disc of the second segment marked beyond
the middle with two rounded patches of sparse whitish appressed hairs, elsewhere
with blackish pubescence, the lateral and ventral margins of the second, third,
and fourth segments, and the mid-dorsum of the third, fourth, and fifth segments
fringed with denser silvery pubescence, hairs of apex of abdomen black ; pygidium
closely granular. Spines of the legs black, less prominent than in the female of
obscura.
Length, 8 mm.

Described from a single female specimen collected in the Trans-
Pecos region of western Texas.
Although agreeing in general with obscura, this species is mark-

Wholly black, with black and whitish pubescence ; mandibles robust bidentate ;
eyes rounded, facetted, ocelli minute ; marginal cell of the blackish wings bluntly
pointed.
Male. Uniformly black over all. Head transverse, somewhat wider than the
thorax, somewhat produced behind the eyes and obtusely rounded to the nearly
straight hind edge, contiguously and rather deeply punctured ; clypeus short,
broadly emarginate at the middle; eyes prominent, more or less irregularly
rounded, anterior ocellus minute, posterior ones rudimentary, represented by two
smooth plane areas; antennae reaching to the middle legs, the scape slightly more
than one-half the distance between the eyes, gradually bent at its outer third,
closely minutely but deeply punctured and clothed with erect and decumbent
black hairs, basal joints of the flagellum, including the pedicel, equal in length,
square in outline; hairs of the head erect, blackish, on each side of the vertex,
at base of mandibles, and on the occiput whitish. Prothorax with small, deep,
dense punctures, those of the mesonotum slightly less closely placed, scutellum
finely rugoso-punctured, pleurse sculptured like the mesonotum, metathorax
reticulate, marked with a median line abbreviated in front and behind ; the
vestiture of the thorax consists of short erect hairs, whitish along the sutures,
the tegula? and the base of the wings, sparse on the metathorax, and blackish
elsewhere. Petiole of abdomen somewhat triangular in outline, the front angles
dentiform, sessile with the second segment ; seen from the side, it is not nodose
and scarcely constricted from the second segment, rather closely punctured like
the second segment, but the punctures well separated, ventral carina reduced to
a small bisetigerous tubercle; remaining segments more finely and densely
punctured, ventral segments sculptured like the dorsals, pygidium finely mar-
gined, finely rugose. The sparse and erect hairs of the abdomen are dirty white
except on the last three dorsal segments, where they are black. Femoral hairs

This continues basallyjust within the second submarginal as a subhyaline streak,
crossing the center of the first submarginal and ending at the base of the stigma.
Veins and stigma black, marginal cell longer than the first submarginal, bluntly
acuminate, second submarginal shorter than the first, strongly narrowed toward
the marginal, receiving the recurrent nervure at the middle. In one specimen
the pentagonal third submarginal and the third discoidal are vaguely denned, in
the other wholly wanting.
Length, 7.25-10.5 mm.
Two males. Forest Hill, Mass., August 31, 1898 (Samuel Hen-
shaw), and Woods Hole, Mass., August, 1900.
Henshawi is placed with the species of the group pennsylvanica
because of its rudimental eyes and the neuration of the wing. It is
quite different, however, from the other males of the division in the
form of the first abdominal segment, which is quite sessile with the
second, as in the females. If this character be considered of more
importance than the other, the species would be placed in the West-
ern group anthophorce with the species adonis Fox, or thamyras Fox.
From these slender species the new form is obviously far removed.

Group imperialis.
The species of this group and of the next are closely related,
forming the old genus Photopsis of Blake as far as the males are
concerned. Were it not for the numerous species here included, it
would be well not to attempt to subdivide this group, at least not
on the grounds taken. The division into genera, such as Odonto-
photopsis, is equally untenable, as the sexual character chosen from
one sex is subject to great variation. For this reason the species
AMERICAN HYMENOPTERA. 305
we have seen are grouped together, but some relationship at least
is expressed in the following key for the separation of the males.
The descriptions of the new species have been interpolated as near
to their relatives as is practicable. The number of undescribed
forms occurring in the Southwestern States is remarkable. The
males are caught mostly at lights which they seek in their nocturnal
flights. The females, however, are much more seclusive, and have
to be sought for on the hot, arid sand during the day-time.

Numerous specimens, Austin and Fedor, Texas. The punctuation
of the head and abdomen is variable but correlated, — the head
punctures are rather fine in some specimens and close in others.
When the head is finely punctured the second abdominal segment
is smooth, otherwise it is punctulate with scattered punctures. Some
specimens have the abdomen rufous. Several distinctive characters
of the Texas specimens are obvious and may be noticed : the bi
sected area of the metathorax is as long as three areoles ; the outer
cubital vein is attenuated before and behind, while the inner cubital
is evanescent posteriorly; the marginal cell is clouded toward the
stigma; and the mesosternum has two crenulate ridges.

Mr. Cockerell has sent a large series of what is apparently this
species, collected at La Cueva, Organ Mountains (altitude 5500 ft.),
September 4th ; at Mesilla Park, June 8th ; and at Arrogo, near
La Luz, August 23d, New Mexico. All the specimens were taken
at light.
The shape of the petiole of the abdomen is subject to variation,
but as the forms otherwise grade into each other, we can be certain
that all belong to a single species. Some specimens have the petiole
subnodose and punctate, as in the imperialis group, while others
have the first and second segments of the abdomen nearly sessile,
the first being almost impunctate.
76. Jlutilla hamata sp. uov.
Male. Eufo testaceous. Head rounded behind, sparsely punctulate, mesouoturu
deeply and closely punctured, metanotuiu reticulate over all, mesosternum with
two transverse obliquely pointed teeth, petiole impunctate, sessile with the
impunctate second segment, two submarginals
Eufotestaceous; rather slender. Head broadly rounded and produced behind
the eyes, nearly impunctate and very sparsely hairy; ocelli moderately large,
the hind ones a little further from each other than from the eyes. Midway be-
tween the front ocellus and the base of the antennae is a punctiform depression
which extends forward to the base of the clypeus as a narrow groove ending in
the transverse basal ridges of the clypeus; mandibles stout, blackened at the
tips; antennae concolorous with the body, short, the scape not paler, short and
stout, punctured and provided with very short and sparse bristle-like hairs-
Prothorax eonfluently rugosely punctate; mesouotum with close deep punctures,
the grooves but slightly abbreviated in front; scutellum contiguously and deeply
punctured ; metathorax moderately reticulated over all ; punctures of meso-
pleurse becoming broader towards the coxae; mesosternum with two strong

roughened by small transverse ridges. Petiole of abdomen very finely and
sparsely punctulate, broadly sessile with the second segment, its length about
equalling its breadth, the front angles bluntly dentiform, the ventral surface
provided with a A-shaped carina, which is emarginate before its anterior termi-
nation; remainder of abdomen impunctate; pygidium broad and rather blunt,
very finely aciculate. Hairs of thorax and abdomen sparse, dusky; abdominal
segments except the first provided with a thin fringe of white plumose hairs.

One male collected by Mr. C. H. T. Townsend at La Cueva,
Organ Mountains, New Mexico. Altitude about 5300 feet. The
insect was taken at light on the 9th of September. The species
seems to come near juxta Blake.

Three specimens from Texas, one from Austin, the others without
definite locality label (M. C. Z.) ; and three from New Mexico
(Saint Augustine, Las Cruces and Arrogo ; Cockerell), appear to

Judged by its poorly defined pygidium, this species would be
grouped with the species about balteola, but as it has no other
relationship with these) and is obviously allied to the new forms

97. Mutilla Xiij i Blake, var. hollensis, var. nov.
Several males collected during different years at Wood's Hole,
Mass., differ from the western form of Sayi in their coarser sculp
ture, although agreeing in color. They may be described as follows :
Head densely but finely punctured ; antenna; black, t lie scape clothed with
short blackish pile and with a rufous apex, third and fourth joints of antennae
equal. Mesothorax with five impressed smooth lines, the median one cuneiform
and extending only a short distance in back of the collar, the intermediate pair
entire, deep, the outer pair abbreviated anteriorly; scutellum reticulately punc-
tured, the reticulation of nearly the same structure as the punctures at the
hinder portion of the mesothorax ; dorsal groove of the metathorax short,
extending less than onedialf the way to the middle; tegulae impunctured,
polished. First segment of abdomen black, closely punctured, its ventral keel
acutely produced in front and annulate near the middle, second segment testa-
ceous, finely and remotely punctured on the disc, laterally and apically the
punctures become stronger and denser, and on the impressed apical margin
become minute and dense, almost scabrous. The impressed margin and the
remaining segments of the abdomen are darker ferruginous. Pubescence arising
from the ferruginous chitin black, except that of the last two segments and the
venter, which is whitish.
Specimens of Sayi from Nebraska are in the collection of the
Museum of Comparative Zoology- A light-colored specimen was
found flying in a gravel-pit in Lake County, 111., September. Carini-
ceps vesta, ferrugata and sparsa were the only females discovered in
the vicinity after diligent search. Can this be the male of one
of these?

contributed by Mr. Cockerell.
110. Brachycistis inaequalis Fox (10).
Two specimens, sent by Professor Cockerell as collected at Saint
Augustine, New Mexico, differ slightly among themselves and from
the description of inoequalis. Although these differences may appear
striking, it seems well not to regard them as belonging to different
species, in view of their otherwise similar structure, size, and con-

tour of body. Moreover, as they were taken together, the differences
in this case do not seem to be of specific value. Briefly, the points
of difference between the two individuals may be stated thus:
a. Head brown ; ocelli large, the distance between the eye and
hind ones less than the diameter of an ocellus ; stigma fuscous,
marginal cell projecting beyond the stigma by nearly the width of
the latter.
b. Head concolorous; ocelli small, the distance between the eye
and the hind ones considerably greater than the diameter of ocel-
lus ; stigma black, marginal cell projecting from it by less than
one half the width of the stigma.
These specimens differ from the description ofincequalis as follows :
antennae not darker; marginal cell longer, second submarginal
longer than the third, third submarginal subquadrate, but higher
than long.
The petiole of the abdomen is highest just behind the middle, and
then is flattened to the tip, which seems to be different from the
conformation in huequalis. Until the specimens are compared with
the types of Mr. Fox's species it would be unwise to found another
species on them.
111. Brachycistis glabrella Cresson (12).
Twenty-two specimens, variable in the length and shape of the
petiole of the abdomen. Alberquerque, Silver City, Arrogo, and
Organ Mountains, New Mexico, taken at light (Cockered) ; New
Mexico, Texas (M. C. Z.).

ous specimens.
113. ' Brachycistis indiscretus Fox (16).
Eight specimens, taken at light at Mesilla Park, May (Cockered ),
appear to belong here. The variability lies in the sculpture of the
mesonotum, which is generally very finely granular and with a
broad, shallow dorsal groove, and in the neuration of the wings.
The third submarginal is inconstant as to form, ranging from a
nearly closed circle to a subquadrate cell larger than the second
submaro;inal.
AMERICAN HYMENOPTERA. 329
114. Brachycistis cremastogast-er sp. nov.
Male. Head castaneus; thorax, abdomen, legs and antenna; pale rufous,
pubescence rather sparse, dusky; ocelli large, the hind ones nearer the eyes than
their diameter, the distance between them twice their diameter, their hind edges
connected by a deeply impressed line; clypens slightly and broadly produced at
the middle; antennal scape snbequal to length of flagellar joints, punctures of
head sparse and fine, occiput but little produced and truncate. Mesonotum and
scutellum with fine scattered punctures, mesosternal punctures slightly stronger,
mesopleural punctures close; metatborax smooth above, very slightly roughened,
almost smooth, posteriorly. Petiole of abdomen cam pan u late, strongly nodose,
depressed above, constricted from the second segment, but little longer than its
greatest breadth, impunctate except for a set of close punctures posteriorly on
the sides, ventral segments somewhat darker. Femora rufo-castaneous, tibise and
tarsi more or less pale. Wings clear hyaline, veins testaceous, stigma fuscous,
marginal cell somewhat more than two-thirds the length of the stigma, second
submarginal triangular, its sides ending near the base of the marginal, its length
on the cubital less than the length of the trapezoidal third cell, third submargi-
nal longer than high.
Length, 10 nam.
Two specimens, indefinitely labelled " Texas," from the Andrew
Bolter collection in the Chicago Academy of Science.
This species will lead to triangularis Fox in Mr. Fox's table, but
it differs from the description of that species thus: pubescence
sparse, almost wanting; metatborax nearly smooth ; petiole impunc-
tate except posteriorly on the sides, where it is finely punctured ;
third submarginal longer than high and longer than the second.
The head is darker, and the size much larger.

A HOLOGRAPH OF THE NORTH AMERICAN
PHORID,E.
BY CHARLES THOMAS BRUES, M. 8.
The present work was begun several years ago, by Prof. J. M.
Aldrich, of the University of Idaho, by whom all the material was
collected. At that time a number of the new species were described,
but owing to work on his catalogue of the North American Diptera,
Professor Aldrich was compelled to discontinue work on the Phorhhe.
At his suggestion, the collection was sent on to me, together with the
descriptions of new species already prepared. In the text I have
placed such descriptions in quotation marks and the initials J. M. A.
after them in parentheses. This signifies that the original descrip-
tion was drawn up by Professor Aldrich.
The material was derived from various sources. A large portion '
of it was collected by Professor Aldrich in Dakota, Idaho, and at
Lawrence, Ivans. A large number of the eastern species were col-
lected by Mr. C. W. Johnson, and many from the middle west by
Dr. William M. Wheeler. Acknowledgments are also due to Dr.
Garry de N. Hough for many eastern and southern forms, to Mr.
A. L. Melander for Texan species, to the National Museum for the
loan of some types, to the University of Kansas, Stanford University
and Cornell University. Specimens have also been obtained from
Dr. Nason, Dr. Kertesz and Mr. Trevor Kincaid. The West Indian
forms were loaned by the British Museum.
I have examined the types of Loew's species in the Museum of
Comparative Zoology at Cambridge, the types of Prof. Aldrieh's
West Indian species (loaned by the British Museum), as well as the
types of some species described by Coquillel and those by Lintner
and Felt. An European collection identified by Strobl has been a
great help in detecting the identity of certain American and Euro-
pean species.
A set of types of the new species described have been placed in
the U. S. National Museum.
In conclusion I wish to express my most sincere thanks and
appreciation to Prof. Aldrich for his many valuable suggestions and
criticisms, as well as for his generosity in placing the collection in
my hands.
TRANS. AM. ENT. SOC. XXIX. OCTOBER, 190o.
332 CHARLES T. BRUES.
The family Phoridae form a very readily recognized group of flies.
All are of minute or rather small size and extremely active. They
separate themselves sharply from other Diptera by their peculiar
antennae and wings; the former consist of apparently a single joint
which bears a long three jointed arista ; the wings are provided with
two distinct kinds of veins, — a series of very thick ones anteriorly,
which reach only half way to the wing tip, and a series of three or
four much lighter veins, which pursue a longitudinal course and are
distributed over the discal portion of the wing.
There are known at the present time about one hundred and
twenty five species from various parts of the world. Of these about
one- half are described from Europe alone, while the greater portion
of the remainder belong to the North American Fauna. There is a
close connection between the European and American species, many
of them being common to both continents. From the large number
of species that are found in every locality which is carefully exam-
ined, it is probable that the number of living forms is greatly in
excess of those at present known, perhaps four or five times as
great. Some of the well known species have a very wide distribu-
tion. A few of the forms originally described from Europe have
Hiice been found in practically all parts of the holarctic region. A
wide distribution seems also to be the rule among the few tropical
species which I have examined.
The members of the family are all small and many of them have
a more or less hump-backed appearance, due to a great development
and arching of the thoracic dorsum. The head is more or less
rounded or hemispherical in shape; the compound eyes are well
separated above and on the front, while the ocelli, which are absent
only in some wingless forms, are placed in a triangle on the vertex.
The front, which is from one-half to one fifth the width of the
head, is nearly always (except Gymnophora and Platyphora) pro-
vided with several transverse rows of strong marochaetae or bristles.
The antennae are placed in cavities at the lower edge of the front,
their insertion varying greatly on account of the extreme difference
in the length of the front in the various species. The antennal cavi-
ties are sometimes more or less coalescent, but usually remain sepa-
rated as lateral depressions. The antennae are composed of three
joints; of these the first is exceedingly small, and the second is
enclosed in the third, so that under an ordinary hand lens they
AMERICAN DIPTEKA. 333
appear as single-jointed. The third joint is very large and gener-
ally sherical or oval in form, although in some genera (Conicera,
Hypocera and Melaloncha, etc.) it may be elongated and drawn out
into a point. The arista is composed of two short basal joints and
a long, usually more or less plumose third joint; its insertion may
be either dorsal or terminal. The palpi are nearly always large
and clavate, with a series of strong bristles along their outer margin.
In the males of some species the palpi are much enlarged, or they
may be destitute of the characteristic bristles. The proboscis is
usually of moderate size and soft consistency; in some forms, how-
ever, it is very strongly chitinized, ami in a few others it is greatly
elongated or swollen.
The thorax is well developed in the winged forms, and is often
considerably arched above, so as to partly conceal the head ; again,
in the wingless females of some genera it is exceedingly small and
often shorter than the head. The dorsum usually bears rnacrochaetse
along the sides, medially behind and on the scutellum. The meta-
thorax is very short.
The legs are large and strong and well adapted to jumping. The
anterior coxa? are much elongated and more or less freely movable
at the base, The four posterior ones are connate with the thorax.
The femora, especially the hind ones, are often exceedingly stout
and flattened. The tibise of all the legs may bear either rows of
setulse or large, strong, single, paired or serial macrochaeta? on the
outer side before the apex. Often part of the tibiae and metatarsi
are covered with close comb-like rows of flattened bristly hairs.
These are very characteristic of the Phoridae. Tibial spurs and
tarsal claws are usually present, although the former may rarely be
absent. The empodia and pulvilli are nearly always present, but
are wanting in a few of the genera. Peculiar modifications of the
legs are rare, and when they do occur apply only to the tarsi and
femora. The femora may be extremely flattened, and the tarsi may
be flattened or swollen. The wings are present in the males of all
genera so far as is at present known, but are absent or very much
reduced in size in the females of quite a large number of the genera.
Their unique venation when present serves at once to distinguish
them from any other known Diptera.
The wings are large and are folded flat on the back when
not in use. The costa is thickened along its basal half to form

the costal vein. Below this is the first longitudinal, which re-
mains separated from the costa until near its tip, where it curves
upward and meets the costal vein ; near the base of the wing it is
connected with the costa by the short humeral cross-vein. Just
beyond it and anterior to the first vein is the mediastinal or auxiliary
vein, which is often obscure or completely absent in some forms.
The third vein is usually quite stout, and meets the costa at its
apex. The second vein is short (absent in many forms), and is
an anterior branch of the third. It usually meets the costa near
the tip of the latter. The costa is bristly except in a very few
cases, as is also the root of the wing behind. The four discal
veins are usually considered as the fourth to seventh longitudi
nal veins, and are always more delicate than the basal veins ;
occasionally the last (seventh) may be absent. As a rule, the wings
are hyaline or but slightly colored, but in some few European species
the anterior border is strongly infuscated. Peculiar wing pores have
been described, which are upon the apical portion of the third vein.*
These pores are very numerous in Phora pachyneura Lw., in which
case they extend over the apical three fourths of the third vein. The
females of many genera have more or less vestigial wings. In
such cases the venation is obscured or obliterated, and the wings
often assume grotesque forms or are ornamented with enormous
bristles {e.g., Acontidoptera and Xanionotuin) ; in another group 01
genera the females are completely, destitute of wings. Even the
halteres are wanting in some wingless females.
The abdomen is of the usual form, generally more or less conical
in the female, and often with a conspicuous hypopygium in the
male. The ovipositor of the female is generally soft and delicate,
* The following remarks upon the wing pores are from Felt, 10th N. Y. Kept.
"An additional character which may prove to be of specific value is found in the
number and location of certain ' pores ' or pore-like structures. The pores, four
in number (i. e., in Aphiochieta albidohalteris), occur in a slightly curved row along
the middle on the outer side of the second heavy vein, where it anastomoses with
the costal vein ; a short stump extends beyond the anastomosis and inclines a
little away from the costa.
''The pores are less than half their diameter apart, the last one being close to
the apex of the stump. Each consists of a depression, surrounded by a raised
circular ring of chitin. These pores must not be confounded with the scars on
the costal vein when a bristle is removed ; they appear to have no connection
with either bristles or setae."
AMERICAN DIPTERA. 335
but in some forms < e. g. Apocephalus, Melaloncha) it is strongly
chitinized and adapted to piercing.
The adult flies are very active and make but little use of their
wings, using them only to fly for short distances. When in motion>
they run about with a peculiar jerky, hopping motion which makes
them readily recognizable at a glance. They may often be captured
in sweepings from damp places, or running about on the ground
among decaying leaves or near carrion. Very often they may be
seen on windows. The numerous species which are parasitic on ants
are usually seen only in or about the nests of their hosts.
The anatomy and transformations of the Phoridse have never been
described with any amount of detail. I give below the description
of a larva which is a species of Phora that was found by Hubbard
in the Mammoth Cave, Kentucky.
The larva is cylindrical, narrowed in front, more suddenly narrowed behind.
Head small, rounded, convex, deeply inserted in the thorax ; above, on each
side, an acute, three-jointed tubercle; in front, a second pair of very minute
tubercles, separated byasutural line, which branches below them ; space between
the branches of the Y-shaped sutures excised, inclosing: the buccal opening, which
appears as a dark transverse slit. Three thoracic segments smaller than the
abdominal segments, retractile, bearing at or near the anterior border a row of
acute tubercles or spines; the prothoracic with a pair of tubular spines arising
from depressions at the middle of each side. Abdomen of nine segments, each
with three folds on the doi-sal surface, the posterior fold bearing a row of spines,
similar to those on the thorax; sides wrinkled, with tubercular prominences
between the segments, and one or two spines anterior to those of the dorsal row ;
ventral surface, each segment with three tranverse ridges, one median, slightly
in advance of the two lateral ridges; the last segments smaller, the terminal
with an anal projection consisting of two large retractile tubercles, directed
upward, and bearing spiracles, surrounded by six radiating spiny processes.
Color dull white, darker at the extremities. The pupa is visible through the
skin of the larva, which becomes an indurated puparium, light red in color,
oval, pointed at the ends, smooth and convex beneath, more depressed on the
dorsal surface, which is margined, with the segments indicated by ridges. The
extremities of the puparium show the parts of the larva unchanged.
It appears from De Meijere's account (1901) that the larva of
Lonchoptera, although quite different in external form from that of
Phora, resembles it in many ways. Osten Sacken (1902) has also
recently given reasons for considering the Phoridse and Lonchop
teridse rather closer to the families included in his superfamily
Energopoda than to any other Diptera. He states specifically,
however, "A real affinity with Phora does not exist anywhere." De
Meijere thinks, from a study of the larva of Lonchoptera, that the
TRANS. AM. KNT. SOC. XXIX. OCTOBER. 1903

latter should be placed as a family of Cyclorrhapha, close however
to the Orthorrhapha. I have no evidence to add in support of
either of these views, but am firmly convinced, from a study of the
mouth-parts and head of Lonchoptera and Phora, that the two
forms are more closely allied than has generally been supposed.
In the following list I have endeavored to give a number of the
species of Phoridse whose habits have been at least to some extent
observed.

GENERIC CHARACTERS.
• Body rather stout, thorax and abdomen stout, well developed.
Abdomen with six segments besides a large hypopygium in the
male, and a three-jointed exsertable ovipositor, which is never
strongly chitinized or horny in the female. Head hemispherical,
the front usually broader than long, with four transverse rows of
bristles, all of which are reclinate; upper three rows each consist-
ing of four bristles, lower row with only a single median pair.
Eyes widely separated, more or less pubescent ; ocelli present.
Cheeks and palpi bristly, the latter often enlarged in the male and
less bristly than in the female. Third antennal joint spherical or
egg shaped, with dorsal arista. Legs stout, the hind femora usually
thickened. Hind tibiae almost always with from one to seven stout
macroch?eta3 on the outer side before the apex, spurs present on the
four hind tibia?. Wings large, mediastinal vein distinct, third lon-
gitudinal vein forked near the apex, costal vein bristly, posterior
wing margin bristly at the root of the wing.
Table of Species.
1. Wings with four delicate longitudinal veins 4.
Wings with only three distinct light veins 2.
* The species which Lioy chose as type for the genus Trisometopia according to
Becker's identification belongs to the present genus in which all the frontal
bristles are reclinate. From Lioy's description one would be inclined to place, it
elsewhere, but I have placed it here, as the type designated by Lioy belongs to
this genus. From the aggregation of types which Lioy indicates for the genus
Phora, it is evident that he either had a very confused idea of the characters of
the species enumerated or was working with wrongly determined specimens.
The first, P. ftavicornis Macq., = maculata Meig., is a true Phora; the second,
P. fuliginosa Meig., is a synonym of Gymnophora arcuata Meig., and some of the
others belong to other genera.

This large and stout species can always be recognized by the
extremely thickened third longitudinal vein, which is thicker than
the costa at its center.
Pliora fratercula sp. nov. (Fig. 3.)
Male. Length 2 mm. Head, thorax and abdomen black. Dorsum of thorax
somewhat shining, sparsely covered with fine black hairs arranged in longitudi-
nal rows. One pair of dorsocentral macrochaetae and two marginal scutellar bris-
tles. Front short, one and three-fourths times as wide as long, with the usual
bristles. Antennae black, of rather large size, strongly black pubescent; arista
pubescent and much thickened at the base. Palpi small, black, the usual lateral
bristles present, well developed. Abdomen dull black, grayish pollinose.
Hypopygium of rounded form, black and slightly pollinose. Legs long
and rather slender, piceous; a little lighter on the anterior coxae and at the
knees. Anterior tibiae with a delicate external bristle at basal third ; middle
legs with a pair and hind legs with a single bristle at the basal third, stronger
than the ones on the anterior legs. Middle tibiae with one and posterior tibiae
with two apical spurs. Halteres varying from light browuish to black. Wings
very slightly infuscated, the costal vein with short, rather closely placed bristles;
reaching to the middle of the wing. First vein ending midway between humeral
vein and tip of costa; fourth vein arising at the furcation of the third, ending
just before the wing tip, not recurved at the tip ; fifth vein ending much behind
wing tip; seventh vein wanting, so that there are only three light veins in
the wing.
Described from two male specimens, collected by Dr. Win. M.
Wheeler, at Jackson's Lake, Wyoming, September 16, 1895.
This pretty species is related to the European P. trinervis Beck.,

but differs by tbe normal form of the palpi, which do not lack the
lateral bristles. It also differs in having a shorter front and shorter
first longitudinal vein. From P. paehyneura Lw. it is distinguished
by its less thickened third vein, longer costal bristles, bristles on hind
tibia?, and presence of only two scutellar bristles.

Thorax and pleurae reddish yellow, ferruginous or darker. Abdomen black.
Halteres yellowish white. Dorsum with only one pair of dorsocentral macro-
chaetae and four distinct scutellar bristles. Head black, palpi yellow. Antennae
reddish yellow or ferruginous, rather small, arista almost bare; cheeks with two
stout, downwardly directed macrochsetse. Second and sixth segments of abdo-
men elongated. Legs yellow, hind femora broadened; fore tibiae with a single

third, and a fourth just before the apex ; spurs of four posterior tibiae well devel-
oped. Wings large, usually infuscated on the apical third ; costal vein reaching
beyond the middle of the wing, conspicuously thickened near the middle portion,
and ciliate with very fine, short bristles. Third longitudinal vein distinctly
bristly as far as the origin of the second ; first vein equidistant from the humeral
cross-vein and the apex of the. costa; fourth vein arising somewhat before the
fork of the third, strongly bent at the base, straight elsewhere; seventh
vein distinct.
Length 3.5-5 mm., wing 4-5.5 mm.
There is a single specimen of this species, from New Hampshire,
in the Osten Sacken Collection at the Museum of Comparative
Zoology in Cambridge. I have seen no European specimens, but
this one agrees perfectly with Becker's description, of which I have
given a translation above. A second specimen is before me. from
Franconia, N. H. (Mrs. Slosson).

knees, tarsi, and fore tibiae yellowish. Front aud thoracic dorsum shining;
halteres yellow. Above the base of the fore coxae are two bristles pointing
downward; lower frontal bristles broadly divaricate. No lines or sutures about
the ocelli. Wings almost hyaline; third vein extending to the middle or slightly

third, and the costa enlarged from there to the tip of the third vein. Fourth and
fifth veins nearly straight at first, then broadly diverging, then coming together
a little, ending equidistant from the apex of the wing; seventh vein indistinct.
Middle tibiae above near base with two setae, the others with one very small one,
which is sometimes imperceptible in the hind tibiae. Dorsum of thorax with one
pair of dorsocentral and four marginal scutellar bristles.
Length 2 mm., of wing 2.2 mm.
The specimens described by Loew were from the district of Co-
lumbia. I have seen only the type specimen which is in the Loew
collection at Cambridge. The species can easily be recognized from
the description.
The specimen referred to by Loew as " var. (?) vena simplici " is
evidently abnormal, for in every other respect it resembles the type
of microcephala exactly. It cannot be a species of Hypocera, al-
though the simple vein would place it there. It lacks the stout legs
and peculiar habitus of the members of that genus. This is the
only case out of many hundred specimens which I have examined
in which there is any such irregularity in the venation.
Phora spinipes Coq. (Figs. 5 and 6.)
Coquillett, Canadian Entomologist, xxvii. 105.
Black, subshining; the palpi, halteres, front and middle tibiae with a large
portion of their femora, also the knees of the hind legs, yellowish ; all frontal
setae pointing upward. Front tibiae each bearing three setae on the outer side of
the basal three-fourths; middle tibiae each bearing three setae in a curved row on
the outer side of the basal half; hind tibiae each with seven setae in an irregular
row extending nearly the entire length of the outer side. Wings hyaline, costal
vein extending three-fourths the length of the wing, ciliate with rather short
bristles; second heavy vein forked near its apex, tip of first heavy vein slightly
beyond the middle between the humeral cross-vein and the apex of the second
vein ; fourth vein curved near its base, then nearly straight, the cell in front of
it scarcely wider than the narrowest part of the cell behind it, seventh vein
distinct.
Length 4 mm.
Hartford, Conn. The original type is a specimen taken by Mr.
S. N. Dunning on April 30, 1893.
Besides the points noted in the original description, it may be
noted that there is a single pair of dorsocentral macrochsetse and
four marginal scutellar ones; the wing veins are light brown ; the
costal cilia extremely short and delicate, and the third vein is finely
bristly.
Singularly enough this is the commonest species at Moscow, Idaho.
I have from this place forty-six specimens, and Professor Aldrich

writes that he could have obtained any number. The length varies
from 2.2-6 mm., of wing the same. On the fore leg I can see only
two setse in any case examined ; on the hind leg they sometimes run
as high as ten. The palpi being so much lighter than the antennse
is a noticeable character ; the latter are black, the former yellow or
brownish. Above the fore coxse is a considerable group of seta?
extending upward so as to coalesce with the infra-humeral group.
Specimens from Idaho were taken in March, April and May. There
is also a single female from Pullman, Wash., collected by Mr. C. V.
Piper.
At first sight it would seem that this species is very close to the
European P. spinosissima Strobl, to which it will go in Becker's
table, but it differs decidedly in wing neuration and tibial cheatotaxy.
Phora olympite sp. nov. (Fig. 7.)
Female. Reddish yellow ; the front, pleurae, metanotum and first three abdorc-
inal segments black.
" Front broad, black, whitisb pollinose and not shining, the lower edge in the
projecting center red; lowest frontal bristles reclinate, moderately divergent.
Antennae red, with long, bare, slender, brown arista, which is yellowish at the
base. Palpi with strong setae, it and the proboscis yellow Close to the eye,
below the antennae on each side, a group of three setse. Dorsum of thorax red-
dish chestnut, hardly at all shining, with one pair of dorsocentral and four mar-
ginal scutellar bristles; pleurae black, indefinitely reddish along the sutures;
halteres wholly yellow. The abdomen presents a very decided contrast in color,
as indicated above; the venter is darker on the apical part than the dorsum.
Legs, including coxae, yellow; tips of tarsi scarcely darker; fore tibiae with one,
hind tibiae with two serial setae about the middle, intermediate tibiae with two
paired setae near the base; hind femora moderately compressed. Wings large
aud long, venation exactly as in P. spinipes Coq." (J. M. A. MS.)

prominent, palpi rufous, with moderately long bristles. Thorax above piceous
black, suhshining, covered with fine, brown, recumbent hairs. One pair of dorso-
central macrochaetae and four marginal scutellar bristles. Scutellum broadly
margined with white behind, the margin extending forward in the middle so
that the black basal part is distinctly bilobed. Abdomen broad, shining black,
each segment narrowly margined with yellowish white; venter yellowish, hairy,
as is also the tip of the abdomen. Legs yellowish, but much infuscated in places,

especially the posterior pair. Anterior tibiae fringed externally with fine setulse
and with a single stout seta near the base on the outer side. Middle tibiae with
a pair of setae at basal third on the posterior side and another lateral one just
before the apex which bears a single spur. Hind tibiae with five long setae on
outer side, a pair of them being placed just below the knee, then follow three
more serially arranged ; there is also a preapical seta and two spurs. Just before
the apex, on the inner face, there is a series of about five comb-like transverse
rows of setse. Posterior femora very broad, shortly ciliated above and below.
Wings subhyaline, very dilutely brownish ; all of the vein? very strong, black.
Costa extending beyond the middle of the wing; first vein ending twice as far
from the humeral vein as from tip of costa. Second vein ending close to third :
costal bristles rather short and densely placed; fourth vein curved at base,
straight at apex; fifth vein straight, ending closer to the wing tip than does the
fourth ; seventh distinct. Halteres pale yellow.
Described from a single female specimen collected on the island
of Grenada, West Indies, by H. H. Smith (No. 172).
This large and handsome species could not be confounded with
any other American species.

yellow, hind femora greatly flattened and enlarged, the middle ones slightly so ;
hind tibiae with an area extending the whole length of the upper side, where the
usual minute hairs are replaced by larger ones, arranged in regular transverse
rows; about sixteen series of these in the length of the tibia. The middle tibia
has a smaller development of the same structure. Fore and hind tibia- each with
one seta below the knee, middle tibiae with two and before the tip with a third
placed at the end of the transverse rows, of which there are about eight. Wings
with a yellowish tinge; costal vein scarcely reaching to the middle of the wing,
first vein ending two-thirds the distance from the humeral vein to the tip of the
third ; fork of third vein slender, not diverging much from the main part, both
together forming a curve, the convexity of which lies toward the apex and rear.
Fourth vein straight, ending considerably before the apex of the wing. Costal
vein with small cilia. Hypopygium of male rather small, yellow. Halteres
yellow." (J. M. A. MS.)
Length 3.4-4 mm., of wing 3.1-3.5 mm.

the front side, besides the spur at apex. Front tibia with a moderately strong
seta in the middle of the upper side. Hypopygium in the form of a rather large
knob. Wings yellowish ; costal vein extending beyond the middle of the wing ;
first vein reaching three-fifths of the distance from the humeral to the tip of the
costal; third vein bare above, except for a single bristle near its base; fourth
vein ending just before the apex of the wing, curved at base, straight at apex ;
fifth vein straight, parallel with the apical part of the fourth." (J. M. A. MS.)
Length 2 mm., of wing 2.5 mm.
One male, Ithaca, N. Y., July 13, 1894 (Cornell Univ.).
Named in honor of Professor J. PI. Comstock.
This species differs from luggeri in not having hair on the upper
side of the third vein, as well as by the number of dorsocentral
macrochsetse. In this species the fourth vein in its first part is much
less sinuous, there is a row of little bristles below at the tip of thje
hind femur, and the third seta of the hind and middle tibiae is not
so near the apex.

The original types of this species were two females from St. Paul
(Lugger).
Besides these, there are some twenty-four specimens in the collec-
tion from other parts of the country, as follows : twenty from Law-
rence, Kans. (two being from the University of Kansas collection
and the others from Aldrich); one from Delaware County, Pa.
(Johnson); one from New Bedford, Mass. (Hough).

Phora cinibicis Aldrich. (Fig. 15.)
Aldrich, Canadian Entomologist, xxiv, 143 il892).
Head black, front broad, below with an obtuse prolongation in the middle;
no ocellar prominence ; at the extreme lower edge of the front, in the middle,
are two bristles directed upward and strongly outward. Antennae brownish
black, palpi of the same color, longer than antennae. Thorax black, pleurae a
little shining ; a group of two or three bristles just below the. prothoracic spiracle
and a pair at the base of the fore coxae. One pair of dorsocentral and four mar-
ginal scutellar bristles. Abdomen wholly satiny black like thoracic dorsum,
except the first segment which is whitish above in the middle; the last segment
longer than the preceding. Halteres black, the pedicel a little yellowish at base.
Fore and hind tibiae with one, middle tibiae with two bristles on the outer side a
little below the knee; the hind tibiae have also a scattering row of three smaller
ones running to the tip ; the tips of the middle and hind tibiae with long spurs.
Legs wholly satiny brownish black, except that the front ones are from the coxae
gradually lighter, ending in brownish-yellow tarsi and that the middle tarsi and
sometimes the middle tibiae are also brownish yellow. Wings subhyaline ; the
third vein forked, fourth vein nearly straight, ending a little before the apex of
the wing.
Length 3 mm., of wing 2 mm.
Three females, Brookings, South Dakota, reared from cocoons ot
Cimbex americana Leach. Emerged May 24, 26, 27. (Condensed
and elaborated from the original description.)
There is also a single additional specimen from New Bedford,
Mass. (Hough, No. 2841 ], and one from Toronto, Can.
This species closely resembles P. nitidifrons, but can always be
readily recognized by its black halteres and by the fact that the
front is foveately punctured, while in nitidifrons it is finely punc-
tured on the sides and smooth medially.

Front dark brown, antennae red, palpi yellowish red, broad at tip, and with
five black setae ; proboscis rather long, yellow. Thorax yellowish brown above
and pure yellow on the sides, middle coxae distinctly blackened, scutellum and
metanotum brown, halteres yellow. Abdomen black above, first segment aud
posterior margins of the following ones yellow; venter yellow except on last
segment. Legs yellow, including front aud hind coxae; tips of the broad hind

five fine setulse, on the hind tibiae a similar series slightly longer are present on
the outer side; middle tibiae with two setae below the knee. Wings hyaline
with a yellowish tinge, at the tip slightly infnscated ; costal vein reaching a little
beyond the middle of the wing; fork of third vein slender, first vein reaching at
least three-fourths the distance from the humeral to the tip of the costal ; fourth
and fifth veins ending equally far from the apex of the wing, the former uni-
formly curved ; seventh vein extremely delicate. Costa with small, fine cilia.
Length 3-3.6 mm., of wing 2.5 mm.
Besides the above, it may be noted that there is only a single pair
of dorsocentral bristles and four equally strong marginal scutellar
bristles.
One female specimen from Charles Harbor, Fla., collected by
Mrs. Slosson and sent by Mr. Johnson ; two specimens, Tifton, Ga.,
October. 16 and 17 (Hough); one, Opelousas, La. (Hough). All
females.
These are somewhat lighter in color than Loew's type, still one of
these has a rather brown thorax. The only material disagreement
is in the pleurae " nigromaculatce" in his description and the middle
coxae (pale yellow in his, very distinctly brown in some of mine).
The type measured only -.6 mm., but most of the species in this
family are extremely variable in size.
This species, as well as divaricata and its variety perplexa, have
on the upper side of the hind tibia a fine, close series of appressed,
short hairs, forming a black line the length of the tibia, but this is
separate from what Loew alludes to as "in latero externo."

Aid rich, Trans. London Ent. Soc, 1896, pt. 3, p. 437.
Antennae, palpi, pleurae, halteres and legs deep yellow; front dark brown or
black, the lower edge yellowish ; thorax above varying from yellow to brown.
Abdomen black or brown, the posterior margin of each segment with a narrow
band of light yellow, which continues more or less as a stripe down the middle
of the dorsum ; venter yellow. Dorsum of thorax with one pair of dorsocentral
niacrochaetae and only two strong marginal scutellar bristles. The other pair is
present, but very small and scarcely noticeable. Anterior tibiae on the upper
side with a row of four setae; middle tibiae with two setae below the knee, hind
tibiae with a minute row of fine hairs along the upper edge, but no setae except at
apex. Hind femora considerably thickened. Wings tinged with yellow ; costal
vein reaching a little past the middle of the wing; first vein reaching three-
fourths of the way from humeral to tip of costal ; the fork of the third vein but
little visible, close to the main part ; male hypopygium very large and conspicu-
ous, bent under.

cent, West Indies, also six males and one female from Grenada, W. I.
All were collected by H. H. Smith and sent by Dr. Williston, who
received them from the Entomological Society of London.
The relationship of this species to incisuralis Lw. is such that the
variety perplexa forms a connecting link between them. Typical
divaricata is more yellow and smaller than perplexa and has a more
tropical range.
P. divaricata Aid., var. perplexa, var. nov.
Coqnillett (P. incisuralis), Canadian Entomologist, xxvii, 104.
Precisely like the foregoing, but differing by its larger size and
more northern range. It is very closely related to both incisuralis
Lw. and divaricata Aid., but can be readily distinguished from the
former by the absence of the four or five small seta? on the hind
tibiae, which characterize incisuralis. It also agrees more closely
with divaricata on account of the extremely small size of the lateral
scutellar bristles, which are large and stout in incisuralis. It would
seem to be an incipient species. This is evidently the form tabu-
lated by Coquillet (loc. cit.) as typical incisuralis.
Three specimens : one from Tick Island, Fla. (Johnson), May 3,
1894, and two from Tifton, Ga., October 16 and 17, 1896 (Hough).

Blaek. slightly cinerascent, thorax somewhat shining, abdomen opaque. Head,
antennae and palpi, blaek. Wings hyaline, slightly yellowish, costa provided with
rather long bristles, nervures dark; third longitudinal vein furcate, the four
longitudinal nervures more slender than the first and third veins. Halteres
black, legs piceous, everywhere covered with short hairs; posterior tibiae with
rather long spurs. Male and female, length 2-2.3 mm.
Eelated to Phora ciliafa, but readily distinguished by the black palpi, longer
costal bristles and different wing venation.
Male. Black, slightly cinerascent, thorax somewhat shining, densely covered
with short, delicate, brown pile; with long macrochsetse along the margin.
Abdomen opaque. Head equal to thorax in width, front wide, black, provided
with long reflexed maerocbEetse and with a median impressed line. Palpi black,
sometimes brownish ; antenna? black. Wings hyaline, slightly yellowish, costa
provided with rather long bristles, nervures dark brown, first longitudinal vein
ending before the third, third furcate at the apex. Four delicate longitudinal
nervures are present, the first of which is rather curved at the base and straight
apically, ending before the apex of the wing, second and third of these four
nervures slightly sinuate, especially the third, fourth almost straight. Near the
front margin of the wing, extending from the third longitudinal vein, is an obso-
lete fold which simulates a nervure. Halteres black ; legs piceous varying to

the chaBtotaxy of the thorax and legs.
nORNIPHOR A Dahl.
Dahl, SB. d. naturf. Freunde. 1898, No. 10, p. 188.
Becker, Monog. Phoridae, p. 84. (1901.)
Front with three transverse rows of four bristles each and two anterior recli-
nate bristles. Ocelli present, third joint of antennae with a dorsal arista, third
vein forked, mediastinal vein obsolete, costa very finely ciliated. Legs bristly,
pulvilli and em podium wanting or much reduced. Front tibiae with a row of
four bristles on the anterior side ; middle tibiae with a pair of bristles near the
base and a third just before the apex, besides the tibial spurs. Hind tibia- some-
what widened, ciliated with fine bristles. Proboscis of the female thin and
greatly elongated, normal in the male.
Represented by a single species from the Bismarck Archipelago,
D. dohrni Dahl.
The close resemblance which this species shows to the American
P. ineisuralis Lw. and P. divaricata and the chsetotaxy of the front
legs is very striking, the present genus being separable from these
two Phoras only by the weakened mediastinal vein, differently shaped
anal angle of the wing and long proboscis of the female. I doubt,
therefore, if it really represents a valid genus. Dahl has mentioned
the relation between Dorniphora and Phora ineisuralis, and sug-
gested that possibly the latter has an elongated proboscis in the
female. The proboscis in this sex is, however, perfectly normal.

Anterior frontal bristles reclinate ; frontal bristles twelve or fourteen in num-
ber, arranged as in Phora. When there are only twelve, either the two anterior
ones or the middle two of the next row above may be wanting. Third longi-
tudinal vein simple, not furcate, often separated or imperfectly fused with the
costal vein at the tip. Antenna' variable, usually ovate or oval, with a dorsal
arista, but sometimes they are elongated and drawn out into a point, and bear a
sub-apical arista. Front sometimes with an ocellar tubercle or with a median
groove. Costal vein ciliated with bristles ; mediastinal vein distinct, seventh

vein present; anal angle of the wing with a series of bristles. Ovipositor of
female retractile, not heavily chitinized or spear-shaped. Legs usually with bris-
tles on the outer side of all the tibiae before the apex, generally one on the fore
tibia, two on the middle, and one, two or none on the hind tibia. Pul villi and
empodia distinct.
All the species which I have included in the present genus are
considered by Becker as belonging to Phora, but all are very distinct
by the characters enumerated above. The species also differ in hab-
itus, being of more robust form and with stouter hind legs.
I have adopted the name Hijpocera, although when described by
Lioy it was improperly characterized. His various types, however,
seem all to belong here, so I have modified the diagnosis as shown
above.

at the base, straight elsewhere ; fifth vein straight throughout ; seventh not very
distinct; apex of wing much nearer to tip of fourth vein than fifth; fourth vein
far away from third, at its point of origin.
Length 5 mm.
Described from a single male specimen, collected at Riverton,
N. J., August 31, by Mr. C. W. Johnson, after whom I take great
pleasure in naming this interesting species.
The present species is evidently closely related to coronata Becker,
of Europe (Becker, Monog. Phor., 41), but differs very clearly in
the frontal cheatotaxy, form and color of antenna? and palpi, and
wing venation.
The antenna? of this species recall strikingly those of Conieera,
yet the insect does not have the habitus or other characters of that
genus. It would seem that the form of the antenna? alone cannot
be a very valuable character for the definition of genera.
This may possibly prove to be the male of ehrmanni, but the dif-
ferences between the two are so much greater than those between
the sexes of the closely related coronata that I have no doubt they
will prove to be quite different species. Unfortunately it is impos-
sible to be absolutely sure.
Hjpocera ehrmanni sp. nov. (Plate vi, fig. 20.)
"Female. A large and robust species; everywhere shining black except the
antennas and palpi, which are deep yellow, the former reddish, with a long black
arista on the oval third joint. Trochanters also somewhat red and the knobs of
the halteres more brown than black, the stems yellowish. Front very polished.
punctured and hairy on the sides, smooth in the middle. Anterior pair of frontal
bristles present, approximate and reclinate; next row above arcuate, the row-
above less so and placed high up. No ocellar tubercle, but the vertex is sharp,

single strong seta before the middle; anterior tarsi with the last joint not flat-
tened or enlarged ; intermediate tibia with two setae at the basal third, also two

tiseriata, with two long and several short apical spines. Wings brownish, especially
toward the tips, costal vein reaching nearly to the middle of the wing, densely
ciliate with rather long hairs; first vein terminating nearly two-thirds the dis-

thorax rather shining and bearing only one pair of dorsocentral macrocha?ta? and
two marginal scutellar bristles. Front wide, strongly convex and shining; the
middle row of bristles forming a straight line very near to the vertex, so that
the distance between it and the lower row is greater than usual ; the lower row
is arcuate and the two middle bristles above the antenna? are lacking. Antenna?,

brown, the costal vein reaching to the middle of the wing, not thickened and
provided with short bristles; third vein not forked, but usually enlarged and
slightly lamellate at apex, finely hairy for its entire length. First and third
longitudinal veins widely separated, so that the first segment of the costal vein
is only one and one-fourth times as long as the second. Fourth vein very
strongly arcuate at its base, straight at apex, approaching near to the fifth at
base.
The female differs in having the lamelliform enlargement of the
third vein more distinct.

District of Columbia (Osten Sacken).
This species is allied to Phora femorata, but is easily to be dis-
tinguished by the color of the antenna1 and palpi.
Besides the original type there is in the Museum of Comparative
Zoology at Cambridge a specimen from New Hampshire. In the
collection before me are two specimens, both collected by Mr. C. W.
Johnson, one from Boston, the other from Montgomery County,
Pa., July 4, 1892; and a headless ? apparently of this species
from Douglas County, Kans.
Besides its lighter color, this species differs from femorata by the
sharper curvature of the fourth vein in the wing.

where the suhapical feathered black arista is inserted. Palpi small, bristly, red-
dish brown. Dorsum rather shining, black, except for slightly yellowish anterior
margin and humeral angles. One pair of dorsocentral macroehsetse and two
distinct marginal scutellar bristles, besides two very small lateral ones. Halteres
reddish yellow. Abdomen yellowish brown except for small subtriangular spots
laterally on each segment; apical segment black. Ovipositor long, exserted,
but nut more heavily chitinized than usual. Legs honey yellow; anterior tibise
with a bristle on the outer side at basal and apical third ; middle tibise with a
pair of stout bristles on outer side at basal third and another smaller suhapical
one, besides a very long spur at apex. Posterior tibise with a single external
bristle at basal third, another subapical one and two apical spurs. Hind tarsi
very long, the first joint bristly below. Wings hyaline, the costal vein black,
other nervures piceous; costal vein reaching to the middle of the wing, velvety
black and considerably thickened throughout; third vein gradually thickened
toward tip, not clavate, and free from costa at tip; seventh vein distinct.
Length 1.8 mm., wing 1.7 mm.
Described from a single female specimen collected by H. H. Smith
on the Island of Grenada, West Indies, (No. 57.)
This is the smallest species of the genus which I have seen. It
is very distinct and not closely related to any described species.

ment of the arista, which is black. Palpi yellow. Post-ocular cilia stout, black,
the lowest three or four, which are below the. eye, being stout and twice as long
as the others. Thorax yellow, paler below and brownish above except for a
rather wide dorsal vitta. Dorsum subshining, with a single pair of dorsocentral
macrochsetse and two marginal scuteilar bristles. Abdomen yellow, first two
segments each with a large, quadrate, very sharply defined, lateral spot 'some-
times absent on the third segment). The spots on the second segment each bear
a tuft of small black bristles at the middle. Ovipositor black at extreme base.
Legs yellow, each coxa with a few stout bristles at the apex, together forming a
stiff hackwardly directed brush. Femora wholly pale, the posterior ones deeper
yellow. Tibiae, especially the posterior pair, spinulose above; four posterior
tibiae each with a single apical spur, that of the middle leg very long, half as
long as the tibia. The posterior tibia? have a fine black line above, and their

tips, veins fuscous; costal vein thickened medially, reaching to the middle of
the wing, its cilia of medium length; third vein furcate; tip of first vein mid-
way between the humeral vein and tip of third vein. Four equally distinct
lighter veins present,
Besides the original types from Texas, 1 have a specimen from
Opelousas, La. (Hough); one from Florida; two from Delaware
Water (lap (Johnson) ; and one from North Mt., Pa. (Johnson).
This is a very distinct species by the form of the front and frontal
cheatotaxy. The abdominal coloration is also very characteristic,
and seems to he quite constant. The species has been bred from
the egg cocoons of the spider Epeira.

Head yellow or dark brown ; the front opaque, gray pollinose. Antennae vary-
ing from yellow to brown, the third joint of only medium size, with an almost
bare arista. Palpi pale, with the usual bristles. In the lighter specimens the
abdomen is considerably darkened above or has wide blackish bands anteriorly
on the segments. Legs yellow, varying to blackish brown, the tips of the hind
femora blackened. Hind tibise lined with black and very finely ciliate. Wings
and veins weakly yellowish brown. Costal vein with rather long cilia, reaching
to only one-third the length of the wing; the first vein ending very close to the
second, so that the first segment of the costal vein is three or four times as long
as the second.

They differ as follows from the above description of European speci-
mens as given by Becker: the body is uniformly darker, almost
black, the halteres blackish, wing veins darker, hind femora unicol-
orous, dark brown in Idaho specimens. Otherwise they seem to be
identical with the European form.

Length 1.75-2 ram. Wholly yellow; second to fourth abdominal segments
black above. Two scutellar and one pair of dorsocentral bristles present. Head
yellow ; front above varying from gray to fuscous; strongly convex and long, so
that the antennae are inserted very low down ; second joint large, ovate, with a
short hare arista. Lower row of frontal maerochsetse arranged in an arcuate
row, widely separated from the second row; the middle pair of anteriorly
directed bristles absent or scarcely developed. Abdomen and halteres dull
yellow; abdomen more or less infuscated, but the fifth segment usually bright
yellow. Hind tibise not darkened at the apex, lined with black and with two
evident rows of fine bristles; hind tarsi black. Wings rather small, almost
hyaline; the costal vein short and weakly bristly, not reaching to the middle of
the wing. First and second longitudinal veins closely approximated.
I have not seen any specimens from this side of the Atlantic. It
has been reported from New Hampshire by Mrs. Slosson, and from .
St. Vincent by Professor Aldrich. :
It should be easily recognized by the short costal vein, which falls
considerably short of the middle of the wing. This is also the case
in pygmcea Zett., but in this latter species it is still shorter and is
only one-third the length of the wing.
Aphiocliseta obscura sp. nov. (Plate vi, fig. 27.)
Length 1 mm. Head brown, thorax and legs yellowish, abdomen black, wings
brown. Front fuscous, sparsely pale hairy, cheatotaxy as usual. Ocellar tuber-
cle and median impressed line very prominent. Antenna? small, yellowish
brown, with a pubescent arista. Palpi yellow, with strong bristles; post-ocular
cilia much enlarged below; two strong cheek bristles. Thoracic dorsum luteous,
rather shining; with one pair of dorsocentral macrochsetse and only two marginal
scutellar bristles. Halteres pale brown. Abdomen black, the posterior edges of
the segments brownish, last segment yellow. Legs luteous. darker toward the
tarsi ; middle and hind tibise each with a single apical spur; the hind ones very
obsoletely ciliated. Wings infuscated; brownish yellow; veins piceous; costa

tip of the costa ; fourth vein evenly curved, fifth and sixth convergent to the
middle, then sharply divergent; seventh vein very close to the anal margin of
the wing.
Described from a single female specimen from St. Vincent, West
Indies (No. 17).
This species is most easily recognized by its brown wings and the
configuration of the light veins.

Male. Length 2.5 mm. Wholly yellow ; thoracic dorsum somewhat shining,
with four distinct scutellar macrochsetse and one pair of dorsocentrals. Head
usually entirely yellow, including the front and greater part of the cheeks,
although the former is sometimes gray pollinose ; frontal bristles all present and
in the usual portions: second antennal joint rather large, with a somewhat
pubescent arista ; cheeks with a row of bristles in addition to the usual two stout
macroch setae ; palpi feebly or not at all bristly. Pleura' below the roots of the
wing and posterior face of middle, coxa- with small black dots. Halteres and
legs yellow, the tips of posterior femora infuscated. Hind tibiae lined with black
and distinctly ciliated, under side of hind femora with black bristly hairs. Wings
tinged with yellowish brown ; the costal vein with short bristles, reaching to the
middle of the wing; veins yellowish brown.
The female differs by the normally bristly palpi, the smaller third
antennal joint, the presence of only very short bristly hairs on the
hind femora.
This common European species is represented in the collection
by specimens from Wisconsin (Wheeler). It has previously been
recorded from North America, — New Jersey (Smith's List); White
Mountains, N. H. (Slosson) ; St. Vincent, W. I. (Aldrich).

wardly directed macroc-hsetse. Abdomen opaque, sometimes brownish or black-
ish above, hut without distinct markings. Legs yellow, the tips of the posterior
femora infuscated ; posterior tibiae lined above with black and delicately spinu-
lose. Wings grayish brown ; costal vein reaching to the middle of the wing, its
bristles very short ; first longitudinal vein very short, so that the first segment
of the costa is no longer than the second ; fourth vein, which arises at the bifur-
cation of the third, somewhat arcuate and terminating before the apex of the
wing.
This common and variable European species is represented in the
collection by numerous specimens from Wisconsin (Wheeler) and
New Jersey (Johnson). Many of the specimens vary much in color
from the type form, but all seem to belong to a single species. Some
have the costal bristles a trifle longer, and spotted or banded abdo
mens, otherwise they are exactly similar.
Apliioclueta atlaiitica sp. nov. (Plate vii, fig. 30.)
Length 1.75-2.5 mm. Yellow, except tips of hind femora and anterior lateral
corners of abdominal segments. Head honey yellow, front thickly covered with
fine black hairs. Ocellar tubercle and median furrow present; frontal chaetotaxy
normal, except that the four proclinate bristles are of nearly equal size and
placed in a curve, besides these there is only a single reclinate bristle in the
lower row, quite close to the eye. At the lower margin of the eye is a row of
stout, downwardly directed bristles, Palpi very small. Antennae yellow, with
a pubescent arista. Thorax somewhat shining, black pubescent, with two scu-
tellar bristles and a single pair of dorsocentrals. Abdomen yellow, the second
to fifth segments with a small black spot at the side anteriorly ; tip of abdomen
black. Second segment with a few weak bristles laterally. Legs yellow, except
the tips of the hind femora, which are blackish ; posterior tibiae with a black line
above and distinctly ciliated with delicate bristles. Wings yellowish, the veins
very strong, fuscous; costa extending to the middle of the wing, with closely
placed, very short bristles, first vein ending a little nearer to the tip of the third
than to the humeral cross-vein ; fourth vein evenly curved.
Described from a number of specimens, — one from Atco, IS". J. ;
one from Natrona, Pa. (Johnson) ; several from Wood's Hole, Mass.
(Melander and Brues).
This species closely resembles flava Fallen, but differs by the
arrangement of the frontal bristles.

Length 2 mm. Wholly yellow; dorsum of thorax very slightly shining, with
only two scutellar and one pair of dorsocentral niacrochsetae. Front yellow or
somewhat gray pollinose. Antennae bright yellow, as are also the palpi ; anten-
nal arista pubescent; two strong macroehaetae just below the eye Abdomen
usually dull yellow ; dorsum often infuscated or yellow, with lateral black spots
on the third and fourth segments. Leiis bright yellow, darker on the tips of the
femora. Hind tibia? with a hlack line above and a row of delicate setulae. Wings
yellowish ; veins of the same color. Costal vein reaching to the middle of the
wing, its bristles rather long; first and second longitudinal veins slightly more
approximated than in flava Fall.
There are numerous specimens from Opelousas, La. (Hough), and
Wisconsin (Wheeler), which agree well with European specimens
of this species. The abdomen varies considerably in color, but
otherwise I can detect no differences.
Aphiocliieta fiiiigicola Coq. (Plate vii, fig. 32.)

Black, subshining, dorsum often brown, antennae and halteres concolorous:
the palpi and the legs, including front coxa?., yellowish. Dorsum with one pair
of dorsocentral macrochaetae and two marginal scutellar bristles. Tibia; destitute
of stout setae on the outer side, hind ones microscopically setulate ; costal vein not
quite extending to the middle of the wing, ciliate with short bristles. Third vein
forked near the apex ; tip of first vein just beyond the middle of the distance
between the humeral cross-vein and tip of the third vein ; fourth vein gently
curved for its whole length, the cell in front of it scarcely wider than the nar-
rowest part of the one behind it. Abdomen bare in both sexes.
Length 1-1.5 mm.
Type locality, Las Cruces, New Mexico (Cockerel]).
Bred from larva? infesting a tree fungus (Trametes peckii), which
was inhabited by coleopterous insects belonging to the genus Cis.
I have examined three female specimens, from the original type
lot, very kindly loaned by the U. 8. National Museum. The hind
femora are quite broad, darkened at the tips and fringed below on
basal half with curved black hairs.
I have a number of specimens from New Bedford, Mass. (Hough),
and Ithaca, N. Y. (Comstock), which come very close to this species.
They differ by their light-colored halteres. These I have designated
as fungicola var. in the table of species.

Yellowish, the color of the thorax often varying into red, sometimes into
brown. Head black; front wide, subeouvex, lightly punctulate, with a very
faint, median, longitudinal, impressed line; the anterior setae directed down-
ward. Antennae black, in immature specimens brown ; palpi yellow. Pleurae
below the wings and between the middle and hind coxae generally with black
markings. Metanotum generally brown or blackish. Abdomen in immature
specimens wholly clay-yellow, in mature ones the first segments, except the pos-
terior margins, almost entirely brown, the remainder with brown sides. Feet
pale yellowish, extreme apex of the hind femora black, front tibiae without
setae, the others with a single row of very minute setulae above. Halteres yel-
low; wings subbyaline, very slightly tinged with grayish yellow; costa with
small cilia; veins brown, second heavy one forked, the fourth light one entire
and distinct.
Original description translated.
Thorax with two dorsocentral niacrochsetse and four marginal
scutellar bristles. Cheeks each with two stout macrochsetfe. First
vein ending midway between humeral cross vein and tip of third
vein ; costa ending beyond the middle of the wing, its bristles rather
short. Palpi of 1 with very small bristles and distinctly enlarged.
This form is related to P. picta Lehm, but differs by its black
head and the longer bristles on the costal vein.
New Bedford, Mass. (Hough); Algonquin, 111. (Nason) ; Knox-
ville, Tenn. (Summers) ; Ithaca, N. Y. ; Austin, Texas, bred from
an artificial nest of the ant Pogonomyrrhex barbatus (Wheeler) ;
Wood's Hole, Mass. (Brues).
This is a species which is widely distributed in the eastern part of
the country, and is by far the most variable one that I have exam
ined. The lateral pair of scutellar bristles varies from extremely
small to the size of the other pair. The color also varies greatly.
The head is always black, but the rest of the body may be pale yel-
low or brownish.
Specimens from New England and the northern parts of the
country are the most typical and agree very well with the original
types at Cambridge, with which I have compared them.

punctured, and with a fine median impressed line; both pairs of proclinate setae
well developed. Pleurae immaculate, dorsum with one pair of dorsocentral
macrochsetae .and four marginal scutellar bristles ; metanotum yellowish. Abdo-
men luteous or ochraceous, hind margin of first segment narrowly, the side and
hind margins of the other segments very broadly black. Legs pale yellow, the

apices of the hind femora black. All the tibia ciliated above with setulae, those
on the four posterior tibia; being very distinct. Wings subhyaline, very faintly
yellowish, costal bristles rather short, veins dark, seventh vein distinct.
Represented by specimens from St. Vincent and Grenada, W. I.
Some of these I have compared with the original types in the Mu-
seum of Comparative Zoology at Cambridge. They agree well in
all details. There are also two specimens— one from Natrona, Pa.,
and one from Philadelphia, Pa (Johnson) — which are less typical,
but belong to this species.

Aldrich, Trans. Ent. Soc. Lond., 1896, 437.
Yellow, lower frontal bristles proclinate, second vein forked, the abdomen, or
at least the dorsal part, reddish orange in color. Front, antennae and palpi yel-
low, arista yellow at base. Dorsum with one pair of dorsocentral macrochaetae
and four marginal scutellar bristles ; thorax wholly yellow; halteres yellow, in
some cases brownish about the apex. Legs wholly yellow, the tarsi scarcely
darker; middle and hind tihiae each with a row of nearly a dozen small bristles,
running down the posterior edge ; hind femora moderately thickened, with a few
very small bristles below near the tip. Abdomen bright reddish-orange in color,
toward the apex and below irregularly blackened. In one specimen, a male, the
reddish color is confined to the base, and there is a well-defined black spot on each
side of the middle of the dorsum. Wings quite deeply tinged with yellow, the
heavy veins reaching far out beyond the middle of the wing; costal bristles very
short ; fourth vein but little curved, ending at or but little before the apex of the
wing ; tip of first vein about equally distant from the humeral cross-vein and from
the tip of the third ; seventh vein distinct to the border.
Length 1.3 1.7 mm.
I have seen the original types from St. Vincent, W. I., and also
several specimens from the Island of Grenada, W. I.
This species is remarkable for the extreme length of the costal
vein and the bright orange-red color of the abdomen. It conies
very close to scalaris Lw., but the costa is longer and its cilia are
stouter and more thickly placed. The lower pair of proclinate setae
are also much weaker than in scalaris.

brownish black. The palpi in the male are enlarged, divaricate, and destitute of
the usual strong setae. Thorax with one pair of dorsocentral macrochaetae and
two marginal scutellar bristles. Wings hyaline, the light veins very slender, tip
of first vein just midway between the humeral and the fork of the third, on the
costa. Fifth vein with a much greater curvature than usual, almost parallel
with the vein before it, ending but little behind the apex of the wing. Legs
rather stout, hind tibia; not ciliate with bristles, or setulose.

This species is distinguished by the presence of four scutellar bris-
tles and the row of small bristles on the middle and hind tibise. It
is a very distinct species.

Length 1.2 mm., of wing 1.3 mm.
Type locality, Brookings, South Dakota. Bred from a cocoon of
Chubex aviericana Leach, which emerged June 1st.
Numerous specimens which agree well with the type. Nearly all,
however, are larger and darker, especially the palpi and legs, which
are often blackish. The wings are also quite strongly infuscated in
fully mature specimens. The palpi are rather broader at the tips
than usual.
South Dakota (type, Aldrich) ; New Bedford, Mass. (Hough) ;
Boontovvn, N.J. (Greene); Hagerm an, Idaho (Aldrich); Ithaca,
N. Y, (Comstock) ; Monterey, Cal. (Wheeler), and Salinville, Ohio.
This species is very readily recognized by its long and narrow
brownish wings and stout posterior tibiae, which are very strongly
setulose.
Aphiochreta furtiva Aldrich. (Plate vii, fig. 39.)
Aldrich, Trans. Ent. Soc. Loudon, 1896, 436.
Female. Head, thorax and'abdomen black ; legs brownish, the tarsi and anterior
tibiae yellow. Front black ; the bristles rather below medium size, the fine hairs
somewhat conspicuous. Antennae blackish, more or less yellowish at base; palpi
yellow. Dorsum of thorax subshining, with one pair of dorsocentral macrochaetae
and two marginal scutellar bristles; pleurae shining black. Halteres black.
Femora in fully colored specimens dark brown, in less mature ones yellowish
brown, the tibiae lighter; hind tarsi almost twice the length of the tibiae. Hind
tibiae on the posterior edge delicately lined with black, on the inner side of this
with a row of about twelve setulae. Wings slightly yellow, the heavy veins
reaching well past the middle of the wing, first vein reaching barely more than
halfway from the humeral vein to the fork of the third, on thecosta; fourth
and fifth veins ending about equally far from the apex of the wing; seventh
vein almost obsolete.

which it differs in not having the hind femora enlarged; the costal
vein is longer also, and the halteres hlack.
Besides the types of this species, I have seen two additional
specimens from St. Vincent. All are females. The altitudes at
which the specimens were captured vary from sea level to 1500 feet.

Male. Length 2.5-3 mm. Thorax and abdomen black, the former somewhat
shining, on the dorsum with unusually thickly placed short brown hairs. Scu-
tellum with only two marginal bristles, and dorsum with one pair of dorsocentral
macrochaetse. Head and antennae black, third antennal joint of moderate size,
with a long pubescent arista. Front gray pollinose, its bristles placed as usual ;
palpi yellow, with long bristles; head with a row of long bristles reaching up
from the border of the eye to the middle of the face. Halteres yellow. Abdominal
segments rather thickly covered with long, perfectly erect, blunt bristles; the
sutures between the segments often yellow. Legs and coxse varying from brown
to reddish yellow; hind femora not especially widened, usually a little darker at
the tips. Wings hyaline; the costal vein reaching about to the middle of the
wing, its bristles very long ; first segment of the costal vein about one and one-
half times as long ss the second.
The female lacks the peculiar abdominal bristles which are so
conspicuous in the male.
There are about forty specimens before me, representing both
sexes of this species, from various parts of the United States, as
follows: New Bedford, Mass. (Hough); Moscow, Idaho (Aldrich) ;
.Michigan; Pennsylvania; Algonquin, 111. (Nason) ; New York
City (Brues) ; Chicago, 111. (Melander).
From this it can be seen that the species is very widely distributed
in this country.
All agree exactly with the description given by Becker of Euro-
pean specimens, of which I have given a translation above.

segments darker. Ocellar triangle defined by a suture which extends down the
front; anterior frontal bristles proclinate. Dorsum of thorax dull, thickly pu-
bescent, with one pair of dorsocentral macrochaeta? and two marginal scutellar
bristles. Costal vein less than half the length of the wing; first vein joining
the costa near its apical third; third vein forked; costa fringed with strong
bristles; fourth vein nearly straight. Fore tibia? unarmed, middle and posterior
ones fringed with stout spines posteriorly, each with a large apical spine. Tarsi
about one-fourth longer than the tibiae. — (Condensed and elaborated from original
description.)
Length 1.92 mm., of wing 2.4 mm.
I have seen two females of the original type lot, which were very
kindly loaned to me by Mr. C. W. Johnson. This species comes
very close to the European rujipes Meig., but the females differ
from those of rujipes in having the fourth vein evenly curved for
its entire length. The costa is also a trifle shorter, not quite reach-
ing to the middle of the wing, and the first vein ends nearer to the
tip of the third.
Type locality, New Brunswick, N. J.
I cannot find the stout spines mentioned in the description of the
posterior tibiae. In the two specimens which I have seen the tibiae
show only a faint suggestion of ciliation.

Male and female. Black, antennae fuscous; knob of halteres yellowish white,
front and middle legs yellowish brown, tarsi brownish, hind legs darker; palpi
yellowish. Wings hyaline.
Ocellar triangle defined by a suture which extends down the front; anterior
frontal bristles proclinate. Dorsum of thorax thickly pubescent, with one pair
of dorsocentral macrochaeta? and two marginal scutellar bristles. Costal vein not
reaching to the middle of the wing. Apex of the first vein nearer to the tip of
the second vein than to the humeral cross-vein ; third vein forked ; costal vein
fringed with strong seta-; fourth vein curved both at the base and apex. Front
tibiae unarmed, middle tibiae with a very long posterior apical spine; hind tibiae
with one long anterior and several short apical internal spines. Anterior edge
of middle and posterior edge of hind tibia? fringed with a thick row of stout
setulae ; internally and closer to the hind margin of the hind tibiae there is a row
of about nine stouter spines on the apical three-fourths. Hypopygium of male
with an irregular dorsolateral plate, the ventral portion of which is prolonged.
Two pairs of organs extend from the plate, an upper straight pair bearing numer-
ous long setae along the entire surface, and a lower pair, slightly curved ventrally
and hearing several long, usually sharply curved seta? at their tips.
Length 1.5-2 mm., of wing 1.75-2.25 mm.
Closely related to P. setacea, but in this species the anterior row
of frontal bristles form a nearly straight transverse row, while in

setacea the middle ones are placed further forward than the lateral
ones. The anterior pair of proclinate bristles are also relatively
smaller and more nearly in front of the middle pair. The costal
vein is much shorter in agarici and the first vein ends nearer to the
tip of the third than in setacea.
The female which Aldrich described as setacea belongs to agarici,
while the male, which is a distinct species, stands as the type of
setacea.
Aphiochieta setacea Aldrich. (Plate viii, rig. 42.)
Aldrich, Canadian Entomologist, xxiv, 144, figs.
Head black, front very wide, with an ocellar prominence and median furrow.
All the frontal bristles large and strong, the four anterior ones proclinate. An-
tenna? fuscous, palpi yellow with black bristles. Dorsum of thorax clothed with
brownish pubescence; scutellum with two marginal bristles. Legs yellowish,
hind pair brownish, posterior tibiae each with a single spur. Coxae with a few
bristles on the outer and apical portions; the posterior coxae with a conical pro-
tuberance on the hind side. Hypopygiuni lying close up under the back part of
the abdomen. Wings slightly grayish, veins yellowish brown, costa reaching
nearly to the middle of the wing, provided with very long bristles. First vein
ending midway between the humeral cross-vein and the tip of the third, fourth
vein not much curved, almost straight except at extreme base and apex, seventh
vein distinct. Halteres yellow.
Length 1.2 mm., of wing 1 mm.
Type locality, Brookings, South Dakota.
This species is closely related to the European P. rufipes Meig.,
but lacks the peculiar bristles upon the abdomen of the male. The
female is very much like rufipes, and when not associated with the
male is almost impossible to distinguish. The costal bristles are,
however, a little shorter and the wing more strongly tinged with
yellow. Many specimens are considerably larger than the type
(2-2.5 mm.)
Aphiochreta rost rata M. et B. (Plate viii, figs. 43, 44.)
Melander and Brues, Biological Bulletin, v, 15 (1903).
Female. Length 1.5-1.75 mm. — Head shining black, especially smooth and
polished on the front and vertex. Front with the normal ehaetoxy, except that
there are only two proclinate bristles at the lower edge. The front is also sparsley
hairy, besides the large bristles; median longitudinal groove and ocellar tubercle
unusually well marked. Antennae black, arista distinctly plumose. Proboscis
piceous, very large and strongly exserted, as long as the head height. It is
rather slender at the base where the rather small bristly spindle-shaped black
palpi are inserted, swollen and bifurcated at the extremity. The bifurcation rs
produced by a splhting of the apex by a horizontal slit in the probocis. Thoracic
dorsum shining, hairy as usual, with one pair of dorsocentral and two marginal
AMERICAN DIPTEKA. 371
scutellar bristles. Abdomen black, nowhere bristly. Legs pale yellow, the tarsi
sometimes brownish, hind tibiae very distinctly ciliated and with a single weak
spur, as have also the middle pair. On the inner side at apex, the posterior pair
have several transverse rows of short black bristles. Wings yellowish hyaline,
the costal vein reaching distinctly beyond the middle of the wing and with very
short cilia ; first vein ending a little closer to the tip of the second than to the
humeral cross-vein; fourth vein evenly arcuate, fifth vein sinuate as is also the
sixth; seventh vein present. Halteres yellowish, blackened at the tips.
The original types from Wood's Hole, Mass., are before me.
This species can easily be recognized by the peculiar form of the
proboscis in the female. The shiny black head and thorax and
contrasting light yellow legs are also quite characteristic.

Male. —Head, thorax and abdomen black, sometimes slightly brownish. Thorax
covered with short brownish pubescence; hut little shining; with a single pair of
dorsocentral macrochaetae and two marginal scutellar bristles. Third antennal
joint of medium size, with pubescent arista. Palpi yellow or reddish brown,
halteres yellow or yellowish brown. Abdomen dull black, sometimes brownish.
Legs varying from yellowish to dark brown ; hind femora rather wide and dark-
ened toward the tips; hind tibiae with a black line above, very delicately ciliated.
Wings often slightly tinged with brown, the veins brown ; costal vein reaching
to the middle of the wing, with long and well separated bristles; tip of first vein
about one and one-half times as far from the humeral cross-vein as from the tip
of the third.
There is a large number of specimens before me which agree well
with European specimens from Strobl and with Becker's description
of this species. Very often the body is brownish and the wings
clear hyaline, but all seem undoubtedly to belong to this species.
The species is very widely distributed in Europe, Siberia, North-
ern Africa and the following localities in the United States: Mas-
sachusetts, Louisiana, South Dakota, Idaho and California. It is
therefore practically circumpolar in its distribution.

the base; arista pubescent. Paipi light yellow, strongly bristly. Proboscis of
female projecting, stout and horny. Thorax shining black, hairy, with one pair
of dorsocentral and two marginal scutellar bristles. Abdomen black. Legs yel-
lowish brown, the anterior pair lighter. Posterior femora ciliated below on api-
cal half, their tibiae without any rows of small bristles on the outer side; four
posterior tibiae each with a single delicate apical spur. Wings hyaline, the costal
vein not quite reaching to the middle of the wing, its cilia short and closely placed.
Third vein far from the costa at its base and forked very near the apex. Tip of
first vein one and two-thirds times as far from humeral vein as from the tip of the
third; fourth vein slightly but evenly curved, recurved at the extreme tip; fifth
vein slightly diverging from the fourth to its tip, which is as far behind the
wing tip as the fourth is before it; seventh vein faint but distinct. Halteres
yellowish in the female, piceous in the male.
I have seen only the original types of this species, which are
from Wood's Hole, Mass.
It is quite easily known by the stout, horny proboscis of the
female and the enlarged third antennal joint of the male.
ApliiocliselaC?) sp. innom. (Plate viii, fig. 46.)
There is a single male, collected by Mr. C. W. Johnson, at Dela-
ware Water Gap, N. J., July 12th, which belongs to an undescribed
species. As the antennae and palpi of the specimen are lost, I have
not undertaken to describe it. It can be readily recognized by the
fact that the hind tarsi are enlarged and flattened (see fig. 46). Dahli
Beck, and coronata Beck, have the fore tarsi enlarged in the male,
but this is the only form, so far as I am aware, in which the hind
tarsi are peculiar. There are no proclinate bristles on the front,
but the absence of bristles on the legs and the presence of a median
furrow on the front indicate its position here. There are only three
rows of frontal bristles, the lower two of which consist of two median
reclinate bristles only.

ciliated with black hairs below near the apex. Spurs of middle and hind tibiae
long. Wings rather long and of even width, costal vein reaching not quite to
the middle of the wing, its cilia very fine and closely placed. First vein ending
two-thirds of the way from the humeral cross-vein to the tip of the costal ; second
vein very close to the third at its tip, i. e., angle of furcation very acute; fourth
vein evenly curved, seventh vein distinct. Halteres pale, black at extreme tips.
I have seen two females belonging to this species, — one from
Frankford, Pa., collected by Mr. H. W. Wenzel, and kindly loaned
to me by Mr. C. W. Johnson, and another specimen from Austin,
Texas, found in a nest of Camponotus maculatus, var. sansabeanus

ally, the sixth segment elongated. Ovipositor narrow, pointed bluntly at the apex,
four times as long as broad. Legs very long and slender; hind tibiae lined with
black above and ohsoletely setulose. Wings yellowish hyaline, very large ; the
costal vein reaching to the middle of the wing, its cilia of moderate length, but
close and very fine. Tip of first vein scarcely nearer to the tip of the costal than
to the humeral cross- vein ; second vein not close to the third at its apex, i. e.,
angle of furcation not very acute; fourth vein slightly and evenly curved:
seventh vein distinct. Halteres pale yellow.
Described from a single female collected at Pine Lake, Wis.,
June 7, 1890, by Dr. Wra. M. Wheeler, after whom I take great
pleasure in naming this species.
The appearance of the female palpi indicates that in the male
these organs will be found to be much enlarged.
The habits of the present species are not known, but close struc-
tural similarity with A. pergandei suggest that it probably lives
parasitically on ants, like the latter.
MEL.4LOXCHA gen. nov.
Moderately large species with long and narrow wings ; head hemi-
spherical ; eyes large. Front narrow, twice as high as broad and
with no median groove or ocellar tubercle. Frontal bristles all
reclinate, in four transverse rows; the ocellar row consisting of four
bristles and the lower ones of two each, the median ones being absent
in these rows. Antennae inserted very low down ; elongate oval,
pointed at tip and with apical arista. In addition to being greatly
elongated they are curved upward, due to an arcuation of the third
joint. Palpi small, with delicate bristles. Thorax and abdomen
normal in the male. In the female the abdomen is very slender
and ends in an asymetrical, sharply pointed, very heavily chitinized
ovipositor. Anterior femora each with a small macrochseta on outer
side just before the knee. Middle tibiae with no bristles except a
single apical spur. Posterior femora rather slender in the female,
stouter in the male. Hind tibiae fringed above in both sexes with a
series of stout bristles ; with two apical spurs. Wings longer and
narrower than usual, costal vein with minute bristles; third vein
not forked at tip; four light veins present. Pulvilli and empodium
well developed.

and interoeellar space black. Front shining, highly polished. Antennae and
palpi lighter yellow, especially the palpi ; arista piceous, swollen at base, finely
pubescent. Palpi with very delicate bristles. Dorsum of thorax piceous black
in the male, brownish yellow in the female. Pleurae black in the male, with a
large yelTow mark just below the humeri ; in the female wholly yellow. Tho-
rax with one pair of dorsocentral macrochfetse and two marginal scutellar bris-
tles. Abdomen of male black, in certain lights with a very fine bluish iridescence
in bands anteriorly on the segments; female abdomen black, with yellow hands
anteriorly on each segment, the yellow being piuiuose with bluish white, as in
the male. Sixth segment twice as long as the others ; ovipositor narrow, black,
polished and pointed ; as long as the rest of the abdomen. Seen from the side,
it is slightly arcuate downward ; from above it is asymetrical, being bent toward
the left just beyond the middle. Legs yellow, except the hind tibise and apical
part of hind femora in the male. Posterior tibiae fringed above in both sexes
with a series of very large bristles, which are longest apically. Wings distinctly
brownish ; nervures piceous, costal vein reaching to the middle of the wing, its
bristles extremely minute. First vein ending a little nearer to the third than to
the humeral cross-vein ; veins four to seven strong, but little curved. Halteres
yellow.
Described from a single male and female from Songo, Bolivia,
South America (Kertesz).
This peculiar form is represented in the collection by a pair of
specimens ( & , 9 ), which were very kindly sent by Dr. Kertesz. Its
general appearance recalls at once the genus Apocephalus ; but it is
seen to differ from the latter by the shape of the front, the simple
third vein, and form of wings and bristles on hind tibise. So simi-
lar are the antennae and ovipositor in the two genera that one can
almost predict that its habits will be found to resemble closely
those of Apocephalus pergandei.
I have seen only the description of the European Phora formi-
carum Verrall, but it evidently has some affinities with the present
species. There are so many differences, however, that a comparison
only could determine their generic relations.
The Phora stylata of Schiner (Novara Reise, Dipt. 224), from the
description, is evidently very closely allied to this species, and I do
not hesitate in placing it here. It differs from 31. pulchella in color
and in the form of the ovipositor, which is provided with two points
at the apex instead of one, as in pulchella.

Front in the male rather narrow, only about one fifth the width
of the head, in the female one-third or one-fourth. Frontal bristles
twelve in number, all reclinate, the lower ones in the middle smaller
than the others ; arranged in four transverse rows, on the vertex
four, then follow three rows each of two lateral bristles; below the
ocelli are two more bristles which are somewhat nearer to "the mid-
dle. Cheeks without bristles. Fore tibiae unarmed, middle tibiae
on the posterior part of the upper surface with a row of very long
setae in the male, four to six in number, in the female only two,
rarely three. In both sexes there are setae also on the fore and hind
tibiae. Dorsum of the thorax with no longer hairs and bristles than
in other genera; velvety; with one pair of dorsocentral macrochaetae
and two marginal scutellar bristles. Third vein of wing not forked,
first running parallel with the costa rather far from it, then making
a somewhat abrupt turn toward it, ending about half way between
the humeral and costal. Auxiliary vein distinct, ending in the
first longitudinal just before the latter turns forward. Antennae
rounded, with dorsal arista, palpi small, bristly only at the tips.
Eyes bare.
The venation and abundance of short velvety hair upon the dor-
sum of the thorax, afford the essential generic difference.

Under the first species I have traced somewhat the history of the
genus. When Meigen became acquainted with Latreille's descrip-
tion of the genus Phora, he considered that it covered the same
ground and withdrew his own genus Trineura*
The genus is represented in North America by three species, one
(aterrima) originally described from Europe and first recorded from
this side of the Atlantic by Walker in his "List" (1849), and

GeofFroy evidently did not apply a scientific name to the species.
Coqnebert probably referred to the species as Musca aterrima, but I
can find no positive statement. The chronological order of the three
publications in 1804 is unknown. Meigen in 1830 regarded his
genus Trineura (1803) as a synonym of Phora Latr. (1796). I
have not ascertained the name under which Walker referred to this
species, but Osten Sacken records it from North America on his
authority. As far as T know, Schiner was the first to use the name
Trineura after Meigen himself discarded it.
Wholly deep velvet-black, in the female a little less intense. Wings hyaline,
the heavy veins usually black, but sometimes only the costa is black and the
others brown, costal vein reaching a little less than half the length of the wing.
Fourth vein only a little curved, ending at the apex of the wing, seventh vein
wholly absent or very indistinct, legs velvety black, fore tibiae and tarsi yellow-
ish or reddish, male abdomen bent in a nearly uniform curve for the most of its
length. Hypopygium in consequence turned partially forward. Front tarsi
not enlarged, middle and hind tibiae with a single external bristle on the basal
half. Middle tibiae of male with four to six bristles on the hind side, female
with only two or three.

Trineura velutina Meig. (Plate viii, fig. 51.)
Meigen, Syst. Beschr. vi, 224, 38.
Like aterrima, but a little larger. In both sexes the front tarsi are distinctly
flattened and enlarged, this is especially noticeable in the female. The costal
vein reaches a little beyond the middle of the wing, and the third vein is not so
far from the costa at its base as in aterrima. Costal cilia long and fine, but not
very close. Hind tibia? with one external bristle; middle tibiae with five to
seveti bristles on the hind side in the male and two to three in the female,
besides one or two bristles on outer side before the middle.
This common European species has never before been recorded
from America. The two species are very closely allied, but easily
separable, by the characters given in the table. Velutina has the
more western range, occurring from California east as far as Massa-
chusetts. Aterrima occurs also in the east, but I have seen no speci-
mens from further west than Kansas and Texas.
Thirty eight specimens. Eight, Leland Stanford University, Cal. ;
nineteen, Moscow, Idaho (Aldrich); four, Los Angeles Co , Cal. ;
three, New Bedford, Mass. (Hough); two, Douglas Co., Kans.

Trineura inoiitaiia sp. nov. (Plate vii, figs. 52, 53.)
Male. Length 1.8-3.5 mm. Wholly dull, opaque velvety black, except coxse,
legs, hypopygium and several spots on the pleura' which are more or less shining.
Front about one-fourth the width of the head, with the normal bristles, the pair
of bristles below the ocelli not so close to the eye margin as the others; lower
part of front on each side of the median line with a vertical row of about five
small bristles which decrease in size upward. Antennae small, oval, with dorsal
arista ; palpi small, bristly only at the tips. Legs black, except the front, which
are brownish yellow. Front tarsi much widened and flattened, wider than their
tibiae, second and following joints as wide as or wider than long; middle tibia
with five or six (usually five) bristles on hind side, on outer side with a single
bristle; hind tibise with a single basal external bristle. Wings hyaline, often
tinged with yellowish ; costal vein reaching well beyond the middle of the wing,
its cilia very short and fine ; fourth vein sharply curved at base, straight at apex,
ending just before tiie wing tip.
Female. Differs by its wider front (one-third the width of the head) and by
having only two bristles on the hind side of the middle tibiae. The front tarsi
are also a trifle wider than in the male.
AMERICAN DIPTEKA. 379
Described from four males and four females, collected in the
Magdalena Mountains, New Mexico, by the late F. H. Snow ; and
from a single male from Kansas.
This species is close to velutina, but can be distinguished by its
shorter costal- cilia, more broadly widened front tarsi, and by the
sharper basal curvature of the fourth vein in the wing.

each with a single apical spur, outer side of middle and posterior
tibiae with two bristles near the base; pulvilli and empodia present.
Antenna in male long and lancet-shaped, turned upward, the arista
rather short, horizontal. In the female the third joint nearly round,
yet with a distinct point where the nasally thickened arista is inserted.

antenna? velvety black, produced into a very long point and reaching consider-
ably above the vertex, feathered on its narrow portion ; arista pubescent,
thickened at base and a little shorter than the third antennal joint. Palpi

opaque and sparsely hlack hairy ; with a single pair of weak dorsocentral macro-
chffita? and a single large scutellar pair. Middle tibia? with a pair of bristles at
the basal third, another single one at apical third and a fourth just before the
apex, besides an apical spur. Posterior tibia? with a pair of bristles at basal
third and a single oue at apical third, besides a long apical spur. Wings slightly
but distinctly infuscated, costal vein reaching nearly to the middle of the wing,
rather more closely ciliated with moderately long bristles than in C. atra ; third
vein not so arcuate as in that species and less widely separated from the costal :

fourth vein curved at base and straight at apex, meeting the margin just before
the apex of the wing ; seventh vein distinct, reaching to the border of the wing.
Abdomen dull black, not bristly; hypopygium reflexed narrowly at the base,
and globular apically, finely hairy below. Legs and halteres black, the femora

Dull black, the palpi and legs often brownish ; dorsum of thorax slightly gray-
ish and shortly black hairy, with two dorsocentral and two scutellar bristles;
tip of male antenna reaching the vertex, the third joint being about two and
one-half times as long as its greatest width. Palpi with rather weak bristles.
Fore tibite with one bristle below the knee, middle tibiae with a pair near the
base and a third just before the apex, which bears a long spur. Hind tibiae with
a pair of bristles near the base and a third one near the middle, apical spur long.
Halteres black; wings hyaline, the costal vein rather strongly ciliated, not
reaching to the middle of the wing, tip of first vein almost three-fourths the
distance from the humeral to the tip of the costal. Third vein considerably
arcuate and distant from the costal for most of its course. Fourth vein uni-
formly curved, ending as far before the apex of the wing as the fifth vein does
behind it. Sixth vein very indistinct at tip, and seventh almost wholly obsolete.
Anterior legs usually somewhat yellowish, but this is rather variable.
The female has the third antenna] joint shaped as in Phora, but with an apical
arista ; otherwise it agrees with the male.
Length 1-1.2 mm.
Numerous specimens of this common and widely • distributed
European species are in the collection, as follows: three males, two
females, Washington, D. C. (Coquillett) ; two males, Horse Neck
Beach, Mass. (Hough); two males, Delaware Water Gap, N. J.
July 8 (Johnson) ; one female, Newark, N. J., June 14 (Johnson) ;
one male, Battle Creek, Mich. ; two females, Canada (Coquillett);
one female, Sullivan Co., N. Y. (Brues).
The North American specimens agree almost perfectly with
Becker's description of European ones except that the legs are
slightly darker and there is much less variation in the size, — only
1-1.2 mm. instead of 1-2 mm., as given by Becker.
Conicera atra, var. neotropiea, var. nov.
There is one male in the collection, from Grenada, W. I., which

as in G. atra, and the third antennal joint of the male falls short of
reaching the vertex. The chsetotaxy and other characters do not
differ, however.

"Palpi little protruding, with short hairs, front hare, very wide,
last joint of antennae globular. Feet bare; posterior femor not
thickened. Wings not ciliated ; marginal nervure bifurcated at its
extremity ; submarginal arcuated, not attaining the apex of the
wing; median nervures sinuous (PI. 24, fig. 5).
" Phora arcuata Meig. differs so much from the others in most of
its characters that I have determined to separate it. The name I
give to this genus makes allusion to the nudity of the principal
organs." — Macquart, /. c, translated.
This easily recognized genus, of which only one species is known,
is distinguished, as above indicated, by the absence of setae on the
front, thorax, wings and legs, in fact by almost absolute nudity. In
front of the wing are two or three fine hairs, and the vertical bris-
tles of the head are also represented by four weak and short bristles
on the vertex, but the apical spines of the tibiae are absent. Scarcely
less characteristic is the course of the fourth longitudinal vein,
which curves forward and ends far before the tip of the wing. The
third vein reaches considerably past the middle of the wing, and the
first ends only a little before the second. The scutellum has only
two small bristles, the dorsum of the thorax being bare otherwise.
The pulvilli and empodia are present.

male moderately large, black, with several small chitinous appendages more or
less concealed.
Length 1.8 to 3.5 mm., of wing 2-3.7 mm. The smaller measurements belong
to the males.
Seventeen specimens; nine from Lawrence, Kans. (a pair taken in
copulation, June 2, 1893, measure 1.8 and 3.4 mm.) ; two from Mil

one Austin, Tex. (Melander) ; two Woods Hole, Mass. (Brues).
All of these agree perfectly with European specimens determined
by Strobl.
Pachyneiirella gen. nov.
Head small; front short, twice as wide as long; with three rows of bristles,
the two upper ones of four each, the next of only a single bristle at each side,
besides two pairs of small proclinate bristles below. Antennae with a perceptible
point at the upper corner where the arista is inserted. Palpi normal, bristly.
Tibiae without setae, even those at the apex being extremely minute. Third
vein of wing not forked, first vein ending less than half way from the humeral
to tip of costal; auxiliary vein distinct but short, ending in the first vein as
usual, fourth to sixth veins very distinct, about half as heavy as the third vein,
with which they appear to effect a direct union, instead of arising as a thin
streak parallel to it; seventh vein distinct but lighter. Costal vein reaching to
about half the length of the wing, ciliated with fine hairs not bristles. Empodia
and pul villi present, the former pectinated as in the female of Wandolleckia.
Anal angle of wing without any bristles.
The heavy fourth to sixth vein, simple third vein and absence of
tibial spurs are the main characters.

Male. Head and abdomen black ; thorax brownish black ; legs, including tarsi
yellow; femora a little darker. Palpi brown, antennae piceous, with strongly
pubescent arista. Bristles of front small except on the vertex. Halteres very
large, brownish black. Dorsum with one pair of dorsocentral macrochaetae and
two pairs of marginal scutellar bristles. Under surface of fore femora with a row
of delicate curved hairs. Pleurae yellowish below. Hypopygium brown, with
two black projecting claspers below, of which the left is fixed and the right mov-
able ; with a brownish lamella or backwardly projecting portion which is bristly.
A yellow band just preceding the hypopygium at the tip of the last abdominal
segment.

SYSTEURA. gen. nov.
Wings with the third vein simple, not bifurcate. Front long, the
sides nearly parallel ; with three transverse rows of reclinate bristles,
besides the four anterior proclinate ones. Antenna? with the second
joint slightly oval, more pointed apically, with a dorsal arista. Palpi
. bristly below. Dorsocentral macroclueta? present. Hind femora thick-
ened ; four hind tibia? each with two long apical spurs, and more or
less spinulose along the outer edge. Mediastinal vein indistinct,
empodia and pulvilli small but distinct.
This genus comes close to Metopina in some respects but is readily
distinguished by the oval antenna?, the long spurs on the tibia? and
the different form of the front, the thickened femora, etc. It also
resembles Pachyneurella but differs by its well developed tibial
spurs, much lighter fourth to sixth wing veins, and the normal form
of the ovipositor in the female.
The generic diagnosis is based upon Phora coceiphila Coq. which
is the only described species possessing the above combination of
characters. It is quite possible, however, that Phora exempta, Beck.
belongs with coceiphila in the present genus. Of this I cannot
positively say, as I have not seen the European exempta.
Myneiira coceiphila Coq.
Cocquillett, Canadian Entomologist, xxvii, 106.
Black, subshining, the under side of the third antennal joint and the palpi
yellowish; halteres whitish. Front legs, including the coxae, light yellow, the
others brown. Wings whitish hyaline, costal vein not extending to the middle
of the wing, ciliate with very short bristles; apex of first vein near the last fifth
of the distance between the humeral cross-vein and the tip of the third vein ;
fourth vein nearly straight, the cell in front of it nearly twice as wide as the
narrowest part of the one behind it. Abdomen bare in both sexes.
Length 75-1.25 mm.
Types. Twenty five specimens in the collection of the Depart
ment of Agriculture, bred in October and November, from larva?
infesting dead adults of Icerya purchasi, collected by Mr. C. H. T.
Townsend at Magdalena, Victoria and Tamaulipas, Mexico.
By the kindness of Dr. L. O. Howard, I am enabled to examine
some of the types. I do not know any member of the family in
which the first and second veins end so near together. The heavy
veins are very short and the light ones relatively long without any
marked curves. The thorax is provided with a single pair of dor-
socentral macrocha?ta? and two marginal scutellar bristlo.

Wings with the third vein simple, not bifurcate; front with not
more than two transverse rows of four bristles above; lower rows
with only two in each row; anterior bristles proclinate. Legs
without any bristles or stout hairs, tibial spurs obsolete; femora
rather slender. Dorsocentral bristles sometimes absent. Antenna?
placed in a deep cavity ; spherical, with an apical arista. Eyes
more or less hairy. Pulvilli reduced or wanting. Ovipositor of
female not heavily chitinized.
This genus, first described by Macquart, was based upon Phora
galeata Halidy. The type species has recently been described care-
fully by Mik (Verb. d. kk. Zool-Bot. Ges., 1880). It is represented
in North America only by the following species.
Metopina pachycondylae sp. nov.
Female. Length 2 mm. Black, antennae and legs yellowish brown. Front
black, not shining, almost inipunetured, distinctly wider than long, with two
rows of transverse bristles, besides the four proclinate ones, and a series of five
on each side next to the anteunal cavity. Antennse yellowish ; second joint
spherical ; arista apical, very slightly pubescent. Ocelli very large. Palpi yellow,
bristly near the tips only. Cheeks with two forwardly directed bristles. Thorax
dull black, finely black pubescent, dorsocentral bristles wanting, scutellum with
two marginal bristles. Abdomen blackish or brownish; pleurae fuscous, varied
with yellowish. Coxae and legs yellowish brown ; slender, without bristles and
almost bare. Wings clear hyaline, heavy veins fuscous, light ones yellow, third
vein ending in a sharp curve before the middle of the wing; costa with very fine
and delicate bristles; first vein ending nearly twice as far from the humeral vein
as from the tip of the third ; fourth vein nearly straight, following veins feebly
curved, seventh vein distinct. Halteres yellow.
Described from one of several specimens, reared by Dr. William
M. Wheeler at Austin, Texas, in November, 1901. The larva? live
as commensals with the larva? of the ant Pachycondyla harpax Fabr.
This form agrees with Becker's characterization of the genus Me-
topina in most repects and no doubt belongs here. The only great
disagreement is in the form of the fifth, sixth and seventh veins in
the wing. It agrees in the form of the antenna?, palpi, heavy wing
veins, arrangement of frontal seta? and bare legs.

Hear! swollen, lentiform, completely chitinized. Eyes extremely
small, on the sides of the head. Ocelli absent. Antenna? of medium
size, arista pubescent. Palpi projecting, not very stout, bristly along
the lower edge and at the tip. Proboscis very long, twice as long as
the head height and geniculate. Thorax rounded, with bristles along
the sides but without any dorsocentral or scutellar bristles. Abdomen
and legs as in Phora, the latter very bare, only at the tips of the four
posterior tibiae with small short bristles. Wings abbreviated, leathery,
resting upon the dorsum of the abdomen, a little longer than the tho-
rax ; with indications of three very thick, rib like longitudinal veins,
which are beset with small black bristles, some of which are notice-
able because of their much greater length. Halteres almost rudi-
mentary.
This was the first of the genera to be described which has reduced
wings in the female sex. It is represented by the single species
P. testaeea Lw. from South Africa. It lives as a guest in the nests
of the ant Dorylus.
CONiUOPTERA Brues.
Brues, American Naturalist, 1901, p. 344.
Female. Small and rather stout species with reduced wings.
Head with very large but rather shallow antenna! cavities. Eyes
small, about half as large as in Phora; ocelli absent. Antennas
rounded, a little pointed at the tip where an apical arista is in-
serted. Front short and broad, anterior frontal bristles porrect ;
besides these the front has only a single ocellar row of four bristles.
Thorax about square; scutellum present, with two bristles, dorso-
ceutrals wanting. Wings short, less than twice as long as the thorax,
with long costal bristles; costa reaching to wing tip, where it meets
the simple third vein. Abdomen entirely membranous except for
four small dorsal plates, the last of which contains the opening of a
gland. Legs moderate.

Becker, Monog. Phoridse, p. 88.
Body broad and much flattened, without any macrochaetae. Thorax
transverse, abdomen small, third vein simple, costa weakly ciliated at
the base.
Broad, flat, shining, frons very broad, the eyes scarcely occupy-
ing one sixth the width of the head. Antennae with the third joint
rather large, somewhat rounded. Thorax broad, flat, rather broader
than the head. Scutellum margined, nearly four times as wide as
long. Abdomen narrower and shorter than the thorax. Legs
stoutish, middle tibiae with two small spines at the tip. First vein
ending just before the third which is not furcate.
(Condensed from the original description.)
This genus is represented by a single species, P. lubbocki VerraW,
from England. As has been pointed out by Verrall, it is readily sepa-
rated from all the other known genera of the family by the lack of
bristles on the body, simple third vein and greatly flattened body. It
has been suggested that this may be the male sex of the genus sEnig-
matias Mien., of which only the wingless female has been described.
This is only a supposition, however.

Type locality, FlagstafF, Arizona. Type No. 6703, U. S. National
Museum.
In regard to its habits, Mr. Coquillett gives the following note :
" Of its habits nothing is known beyond the fact that it occurred on
low vegetation in a locality where no ant- nests could be found, al-
though search was made for them. No stones or rocks occurred in
the immediate vicinity, the nearest approach being the small pieces
of lava scattered about, but these were too small to conceal an
ant- nest."

without wings or halteres. Female with very small eyes and no
ocelli ; thorax small ; abdomen with seven segments. Third an
tennal joint spherical, with an apical arista. Pul villi pectinated,

This genus is represented by a single species from West Africa,
found upon land snails belonging to the genus Achatlna. The spe
cies has never received a name, ami I, therefore, designate it as W.
cooki, in honor of its discoverer Dr. O. F. Cook.
GENERA OF UNCERTAIN POSITION.
Under this head I have attempted to group all of the genera which
have been too poorly characterized to admit of recognition, or which,
for the various reasons set forth under each, will have to be ignored.
IMIKIW Lioy.
1864. Lioy Atti, Soc. Veneti., 77.
" Face often with an impressed line. Frontal macrochretae directed
downwards ; legs setulose, posterior tibiee usually very spinose. Wings
slightly ciliated on the margin ; marginal vein bifurcate at the apex,
submarginal reaching to the apex of the wing, arcuate at the base
and straight at the extremity ; anal vein wanting, median nervure
straight."
" The name refers to the absence of the anal vein."
Type, A. urbana Meig.
According to Becker, P. urbana Meig. possesses four discal veins
and the frontal bristles are all reclinate. If such be the case, Aneti-
rina cannot be retained as a valid genus, which would be of doubt-
ful propriety, anyhow, even if the diagnosis were correct. This must
evidently have been based upon wrongly determined specimens.
OBELOSIA Lioy.
1864. Lioy Atti, Soc. Veneti.. 77.
" Macrocha3ta3 of the front directed downwards, posterior tibia?
with small spines, intermediate ones bare, with a long terminal
spine. Wings ciliated with the marginal vein bifurcate at the ex-
AMERICAN DIPTEKA. 398
tremity; submarginal reaching the apex of the wing, arcuate at
the base straight at the apex. Median nervure straight."
" The name refers to the long spur of the intermediate til>i;e."
Type, 0. rufipennis Macq.
This genus was based upon an unrecognized species of Maequart,
otherwise the diagnosis would apply tolerably well to Aphiochseta (as
would also his Trisometopia). It seems unwise, however, to resur
rect this old name, which is without significance, resting as it does
upon an unrecognizable species; and to modify the diagnosis to suit
a large group of species since described. This would also involve
choosing a new type species for the genus. For this reason I think
it had best lie discarded.
D1PLONEURA Lioy.
1864. Lioy Atti, Soc. Veneti., 77.
" Frontal inacroclnet;e directed downwards, palpi usually broad :
legs setulose, tibia often almost bare; wings with the margin ciliated
strongly. Marginal vein bifurcate at the extremity, submarginal
reaching to the apex of the wing, arcuate both at the base and
apex ; median nervure straight."
" The name refers to the furcate marginal vein."
"Types D. nitidula Meig., D.florea Meig., D. atra Macq."
Of the types chosen for this genus, the first cannot be recognized,
and the type of the species does not seem to be extant (Becker, '01.
71). The second belongs to Phora, having all the frontal bristles
reclinate, and the last, atra Macq., is unrecognizable. Hence the
generic name can only be a burden, and had best be dropped.
LISSOM ETOPI A Lioy.
1S(>4. Lioy Atti, Soc. Veneti., 79.
" Front bare, without macroclnetaj, legs setulose. Wings ciliated
only at the base; marginal vein simple, reaching beyond the middle
of the wing, submarginal reaching to the apex of the wing; median
nervure straight."
"The name refers to the bare front."
" Type, L. nudifrons Macq."
This genus is based upon an unrecognizable species described by
Maequart, and as the characters do not apply in their entirety to
any present known species or group, it will have to be discarded,
TRANS. AM. ENT. SOC. XXIX. (50) DECEMBER. 1903

tentatively at least. It resembles Gymnophora in the partial absence
of the costal bristles but differs by its setulose legs. Possibly if the
type species is ever identified, it may be possible to determine the
validity of the genus.
It is quite possible that Platyphora Verrall may be a synonym of
Llssometopia, as these two genera are the only ones known to me in
which the front is not at all bristly. If this be so then Lisscmetopia
has priority over Platyphora.
M 1IOSI V Lioy.
1864. Lioy Atti, Soc. Veneti., 78.
" Frontal macrochretse directed downwards; vertex with a trans-
verse tubercle, anterior tibiae with two or four lateral bristles, inter-
mediate ones not ciliated ; posterior ones with a lateral bristle. Wings
ciliated, with the marginal nervure simple, extending beyond the
middle of the wing. Submarginal reaching to the apex of the wing.
Median nervure straight."
"The name refers to the occurrence of these insects in forests."
Type, N. incrassata Meig.
The generic diagnosis contradicts the descriptions of Meigen and
others (see Becker, '01, p. 38) of the species chosen as type, as
regards the chsetotaxy of the middle tibia?. As such is the case, the
generic name can hardly be applied with propriety to the group
which happens to agree with a diagnosis drawn up from an incor-
rectly determined species as type, and will have to be discarded.*
HIERONYMUS Weyenbergb.
1886. Weyenbrgh, Tidschr. Ent, xxix.
Antenna? small, placed low down, almost on the border of the
mouth. Proboscis arcuate, strongly hairy, palpi small. Thorax
strongly arched and more or less concealing the head. Legs with
only short bristles; femora long and slender; tibiae broad, each with
two apical spurs and with bristles. Wings very long and wide; costal
vein with short bristles, mediastinal vein not very distinct.
Important characters, translated from Wyenbergh's generic diag-
nosis.
From the above it is impossible to tell the generic relations of this

form, which is represented by a single species, H. pygmceus Wyenb.,
from Cordova, South America. It is, therefore, omitted from the
table of the genera.
PA LLIR4 Walker.
1S59. Walker, Journal Proceed. Lin. Soc, iii, 127.
Mule. Body rather broad, pubescent. Proboscis rather small,
withdrawn; antennae very short, arista very long; scutellum large,
conical, extending beyond the base of the abdomen. Abdomen
nearly elliptical, no longer than the thorax ; legs rather broad,
pubescent, without bristles; wings rather long and broad ; veins of
equal size, costal vein ending at rather before half the length of the
wing, cubital ending at hardly in front of the tip, prsebrachial end-
ing at a little behind the tip, prohrachial ending on the hind border
at half the length of the wing; discal transverse vein straight,
parted by more than twice its length from the border and from the
prsebrachial transverse.
Tins description is worthless as it contains no unique character and
omits many of the necessary ones for distinguishing the well known
genera. As Becker (1901, 90) has already remarked, it is hard to
see what Walker had in mind as distinguishing characters for the
genus.
TERMITOXEN1A Wasmann.
1900. Wasmaun, Zeit. Wiss. Zoo]., Ixvii, 4 Heft, pp. 599-617. Plates.
1901. Wasmann, ibid., Ixx, 2 Heft, pp. 289 298.
"When Wasmann first described this genus (/. c, 1900), he regarded
it as related to the forms of wingless Phoridse for which Wandolleck
had just previously erected the family Stethopathidse and accord-
ingly placed it in this latter family, giving numerous reasons which
seemed to justify such a conclusion.
Later, however, at Mik's suggestion, in a second paper (/. c, 1901),
Wasstnann attempted to remove it entirely from its position near the
Phoridse and assign to it a place near the Muscidse ; not in the Eu-
myidae as Mik suggested, but in a position intermediate between the
Muscidse and the Pxvpvpara in the family Termitoxeniidse. All of
the very close similarities which Dahl had pointed out between Ter-
mitoxenia and the Phoridse were cast aside as merely " wichtige
Aenlichkeiten," while the post embryonic development, which has
been only slightly studied, and the shape and position of the antenna!
cavity were chosen to determine its position. It is so well known as
TRANS. AM. ENT. SOC. XXJX. DECEMBER, 1903
396 CHARLES T. BRUES.
to scarcely need mention that the post-embryonic devevelopment is
not a good character to separate groups, while the shape and posi-
tion of the antenna! cavity are characters which appear in such an
endless combination that we are always open to error in attempting
an artificial division of groups on such a character.
In my opinion the peculiar antennae of Termitoxenia are enough
to prove without a doubt its close relationship to the Phoridae. The
Phoridae are absolutely unique among the Diptera by the structure
of the antennae which have the second joint enclosed in the third.
Termitoxenia has exactly similar antenna?, both in shape and struc-
ture. We must then consider the two closely related or believe that
the similarity is purely accidental, which is scarcely possible. The
com!) like rows of bristles upon the metatarsi of Termitoxenia are
also exactly similar to those of many Phoridse, in which family the
tibiae and tarsi show a great tendency to bear such rows of hairs. I
know of no other Diptera which possess these. Then the shape of
the thorax, the form of the legs, with the long free anterior coxae,
the reduction of the wings and the eyes, the swollen abdomen, with
a very small first and extremely large second segment, all find their
counterparts among certain Phoridae. The probosis has no doubt
been greatly modified to conform with its termitophilous habits.
For these reasons I have included Termitoxenia in the present
paper. While it may represent a distint family, it is evidently
closer to the Phoridae than to any. other Diptera.
CATALOGUE OF SPECIES.
As many of the generic names used in the present paper are new
and necessitate a different arrangement of the species, I have prepared
the following catalogue in which the species are segregated in their
proper genera. North American species are in the larger type,
others in the smaller.

APPENDIX.
Note 1. — Regarding the use of the generic terms Phora and Tri-
teura, Prof. Aldrich, with the assistance of Dr. Henshaw, has looked
up the matter carefully and come to the following conclusion.
The genus Phora was first mentioned by Latreille (Hist. Nat.
Crust, et Ins., iii, 4(14 (1802), where after a brief description of the
-eons Phora, then adds the following : " Exemple. Musca aterrima ;
putris? F." The putris is probably Themira putiris, but as it is put
second and with a query does not affect the real type which is clearh
■nin .
Meigen established the genus Trineura in 1<S0.'5 in [lliger's Maga-
zine, one year after Latreille's characterization of Phora, with the
AMERICAN DIPTERA. 403
same species as type, namely aterrima. Seeing, therefore, that Tri-
neura was a synonym of Phora, some years later (Syst. Beschr., vi.
212), Meigen distinctly says that his Trineura is a synonym of
Phora, which has precedence; it is on this account that lie puts all
the species under Phora, dropping Trinevra entirely.
From these facts it can lie seen that a strict application of the
rule of priority would necessitate the removal of Trineura. As ii
would cause needless confusion, however, to restore Phora to i t>
proper position at this late date, I have thought it best to follow
Becker's recent work and retain Trineura.
